1) A merchant had a diamond, cost of which varies as a square of its weight. The
merchant broke the diamond into 3 pieces in the ratio (based on weights) 4:5:6. When
the pieces were sold he incurred a loss of Rs.444000. What could be the original price of
the diamond?
Options:
a)Rs.750000       b)Rs.665000         c)Rs.600000          d)Rs.675000
Answer: d) Rs.675000.
Solution:
As given, the weights of the broken pieces are in the ratio 4:5:6.
Let the actual weights of broken pieces be 4X,5X and 6X.
Then weight of the original diamond = 4X + 5X + 6X = 15X
Since the cost of a diamond varies as its square of the weight, the original cost will be
(15X)
2
 = 225(X
2
). ...(1)
The total cost of individual pieces will be (4X)
2
 + (5X)
2
 + (6X)
2
= (16 + 25 + 36)x(X
2
) =
77(X
2
). ...(2)
The loss value = (1) - (2) = 225(X
2
)-77(X
2
) = 148(X
2
).
But the above loss value is given to be Rs.444000
Therefore, 148(X
2
)=Rs.444000
X
2
 =Rs.444000/148.
=Rs.3000
Original cost = 225(X
2
) = 225 x 3000
= 675000
Hence the answer is Rs.675000.
2)  X and Y can complete a work in 12 days and 10 days respectively. With the help of Z,
X and Y can together complete the work in 5 days for a total wage of Rs.6000. Then
what wage should be paid to Z for his part of the work? 
Options:
a) Rs.1000         b) Rs.1500        c) Rs.500        d) Rs.2000 Questions/Articles Extracted From www.CareersValley.com
Page 23
Answer : c) Rs.500
Solution:
From given data,
X's 1 day work = 1/12
Y's 1 day work = 1/10
If X,Y and Z would complete the work in 5 days, then Z's 1 day work = One day work of
X,Y and Z combined - (One day work of X + One day work of Y) =
1/5 -[(1/12)+(1/10)].
= 1/5 - 11/60 = 1/60.
Now we have to find Z's share of the salary.
X's share : Y's share : Z's share = 1/12 : 1/10 : 1/60 = 5 : 6 : 1
Z's share of wage from the total wage of Rs.6000 = 1/(5 + 6 + 1) x 6000 = Rs.500
3) Gautam is good in sculpturing. He makes a sculpture of height 4 feet 8 inches and
places them on a sandal pedestal. If the total height of sculpture and the pedestal put
together is 7 feet 3 inches, what is the height of the pedestal?
Options:
a) 2 feet 4 inches         b) 5 feet 2 inches       c) 2 feet 7 inches      d) none of these
Answer : c) 2 feet 3 inches
Solutions:
Total Height = Height of the sculpture + Height of the pedestal
7 feet 3 inches = 4 feet 8 inches + Height of the pedestal
Height of the pedestal = 7 feet 3 inches - 4 feet 8 inches
Writing all the measurements in units of inches we get,
Height of the pedestal = 7 x 12 + 3 inches - 4 x 12 + 8 inches = 87 inches - 56 inches =
31 inches = 2 x 12 inches and 7 inches = 2 feet 7 inches 
4) John, Chief Executive Officer of Infacan , Mumbai drove by his Benz car from Mumbai
to New Delhi. He started at 2 pm and drove at 60 kmph. Around 2.30 pm his personal
assistant called him over his cell phone and told that John had not taken an important
paper with him and sought instructions from him. John advised his personal assistant to Questions/Articles Extracted From www.CareersValley.com
Page 24
send those papers through Don Lee. Don Lee started from Mumbai at 2.45 pm and he
was driving his Hyundai car at 75 kmph. At what time Don Lee will overtake John
assuming they travel at speeds indicated and they do not stop in between?
Options:
a) 5.15 pm        b) 5.45 pm        c) 5.30pm       d) 6.00 pm
Answer: b) 5.45 pm
Solution:
Distance travelled by John before Don Lee starting from Mumbai is 45 km.
Relative speed of Don Lee with respect to John = 75 - 60 = 15 kmph.
Time taken by Don Lee to overtake John = Distance travelled by John before Don Lee
starting / Relative speed = 45/15 = 3 hours
So Don Lee will overtake at 2.45 + 3 = 5.45 hours
5) Raghavan and Krishnan started from Chennai to Mumbai in two different cars at 10
am one day. Raghavan was driving his car at 50 kmph and Krishnan was driving his car
at 40 km per hour. Around 11 am their friend Gopalan started in his car from Chennai
and drove his car at 70 kmph. At what time Gopalan will overtake Raghavan and
Krishnan?
Options:
a) 1.00pm and 12.20 pm            b) 1.30 pm and 12.10 pm 
c) 1.30 pm and 12.20 pm           d) none of these.
Answer: c) 1.30 pm and 12.20 pm
Solution:
Raghavan and Krishnan would have travelled 50 km and 40 km by the time Gopalan
starts at 11 am.
Gopalan is driving at 70 kmph.
Relative speed – Gopalan with respect to Raghavan = 70 - 50 = 20 kmph
Distance travelled by Raghavan when Gopalan started = 50 km. 
To catch up with Raghavan, time taken by Gopalan = Distance covered by Raghavan
when Gopalan starts / Relative speed of Gopalan with respect to Raghavan = 50/20 = 2
½ hours.  Questions/Articles Extracted From www.CareersValley.com
Page 25
Therefore, he will overtake Raghavan at 11.00 + 2.30 = 1.30 pm.
Relative speed of Gopalan with respect to Krishnan = 30 kmph
Distance travelled by Krishnan when Gopalan started = 40 Km.
Time taken by Gopalan to cross Krishnan = Distance covered by Krishnan when
Gopalan started / Relative speed of Gopalan with respect to Krishnan = 40/30 = 1.33
hours = approximately 1 hour 20 minutes
Gopalan is starting at 11 am. So he will overtake Krishnan at 11 + 1hr 20 min = 12.20
pm

10) Briefly can you explain a 'database trigger'?
Answer:
A database trigger is a predefined code that gets executed based on certain events on
tables. For example, a trigger can be written that executes automatically whenever a
particular column gets updated in a table. Though they are memory intensive, they can
be used for critical background tasks to maintain data integrity.
11) Tell a common error encountered by programmers when using stack data structures
without proper precautions?
Answer:
Stack Overflow is a common error when dealing with stack data structures. This occurs
when data is pushed onto stack till a point when there is no further memory is available.
Good programming and understanding of the resource limitations of the underlying
machine can prevent these errors.

13) (Generally) In an application development life cycle, give the proper order of the
following stages: Testing, Test Plan Preparation, Development, and Requirement
Gathering.
Answer:

and Testing.
14) Can you guess why IPv6 (Internet Protocol version 6) addresses came into
existence while still IPv4 is being used by many machines?
Answer: 
The only reason could be the enormous growth in the number of machines using v4
addresses. This forces concerned agencies to raise the address pool by some means.
One of such ways was the introduction of IPv6 so that more machines can be
accommodated.
15) Consider two network layer devices, one operating at network layer and the other
operating at data link layer. In very generic terms, which one is more intelligent? Explain
with example.
Answer: 
Generally a device that operates at a higher layer in OSI model is intelligent. For
example, there are switches that operate at data link layer and some others that operate
at network layer. Simply due to the additional capabilities of the switches that operate in
network layer they can be considered more intelligent. 
16) What is the main drawback when using Hubs in networks?
Answer: 
Hubs are least intelligent devices transmitting whatever data they receive into all the
output ports. Though this behaviour can be favourable in some cases, most of the times
this behaviour results in unnecessary traffic in the network. More network consumption
leads to problems like collision and congestion. Questions/Articles Extracted From www.CareersValley.com

17) In socket communication happening between a client and a server, how can you tell
which one is a client and which is a server?
Answer: 
Consider two network devices communicating through network sockets. In many cases a
client initiates a transaction. For example, your computer could request a web page from
a server. This implies that your computer is initiating the connection and is a client. The
responding machine will be the server. Questions/Articles Extracted From www.CareersValley.com

                            

1) A merchant had a diamond, cost of which varies as a square of its weight. The
merchant broke the diamond into 3 pieces in the ratio (based on weights) 4:5:6. When
the pieces were sold he incurred a loss of Rs.444000. What could be the original price of
the diamond?
Options:
a)Rs.750000       b)Rs.665000         c)Rs.600000          d)Rs.675000
Answer: d) Rs.675000.
Solution:
As given, the weights of the broken pieces are in the ratio 4:5:6.
Let the actual weights of broken pieces be 4X,5X and 6X.
Then weight of the original diamond = 4X + 5X + 6X = 15X
Since the cost of a diamond varies as its square of the weight, the original cost will be
(15X)
2
 = 225(X
2
). ...(1)
The total cost of individual pieces will be (4X)
2
 + (5X)
2
 + (6X)
2
= (16 + 25 + 36)x(X
2
) =
77(X
2
). ...(2)
The loss value = (1) - (2) = 225(X
2
)-77(X
2
) = 148(X
2
).
But the above loss value is given to be Rs.444000
Therefore, 148(X
2
)=Rs.444000
X
2
 =Rs.444000/148.
=Rs.3000
Original cost = 225(X
2
) = 225 x 3000
= 675000
Hence the answer is Rs.675000.
2)  X and Y can complete a work in 12 days and 10 days respectively. With the help of Z,
X and Y can together complete the work in 5 days for a total wage of Rs.6000. Then
what wage should be paid to Z for his part of the work? 
Options:
a) Rs.1000         b) Rs.1500        c) Rs.500        d) Rs.2000 Questions/Articles Extracted From www.CareersValley.com
Page 23
Answer : c) Rs.500
Solution:
From given data,
X's 1 day work = 1/12
Y's 1 day work = 1/10
If X,Y and Z would complete the work in 5 days, then Z's 1 day work = One day work of
X,Y and Z combined - (One day work of X + One day work of Y) =
1/5 -[(1/12)+(1/10)].
= 1/5 - 11/60 = 1/60.
Now we have to find Z's share of the salary.
X's share : Y's share : Z's share = 1/12 : 1/10 : 1/60 = 5 : 6 : 1
Z's share of wage from the total wage of Rs.6000 = 1/(5 + 6 + 1) x 6000 = Rs.500
3) Gautam is good in sculpturing. He makes a sculpture of height 4 feet 8 inches and
places them on a sandal pedestal. If the total height of sculpture and the pedestal put
together is 7 feet 3 inches, what is the height of the pedestal?
Options:
a) 2 feet 4 inches         b) 5 feet 2 inches       c) 2 feet 7 inches      d) none of these
Answer : c) 2 feet 3 inches
Solutions:
Total Height = Height of the sculpture + Height of the pedestal
7 feet 3 inches = 4 feet 8 inches + Height of the pedestal
Height of the pedestal = 7 feet 3 inches - 4 feet 8 inches
Writing all the measurements in units of inches we get,
Height of the pedestal = 7 x 12 + 3 inches - 4 x 12 + 8 inches = 87 inches - 56 inches =
31 inches = 2 x 12 inches and 7 inches = 2 feet 7 inches 
4) John, Chief Executive Officer of Infacan , Mumbai drove by his Benz car from Mumbai
to New Delhi. He started at 2 pm and drove at 60 kmph. Around 2.30 pm his personal
assistant called him over his cell phone and told that John had not taken an important
paper with him and sought instructions from him. John advised his personal assistant to Questions/Articles Extracted From www.CareersValley.com
Page 24
send those papers through Don Lee. Don Lee started from Mumbai at 2.45 pm and he
was driving his Hyundai car at 75 kmph. At what time Don Lee will overtake John
assuming they travel at speeds indicated and they do not stop in between?
Options:
a) 5.15 pm        b) 5.45 pm        c) 5.30pm       d) 6.00 pm
Answer: b) 5.45 pm
Solution:
Distance travelled by John before Don Lee starting from Mumbai is 45 km.
Relative speed of Don Lee with respect to John = 75 - 60 = 15 kmph.
Time taken by Don Lee to overtake John = Distance travelled by John before Don Lee
starting / Relative speed = 45/15 = 3 hours
So Don Lee will overtake at 2.45 + 3 = 5.45 hours
5) Raghavan and Krishnan started from Chennai to Mumbai in two different cars at 10
am one day. Raghavan was driving his car at 50 kmph and Krishnan was driving his car
at 40 km per hour. Around 11 am their friend Gopalan started in his car from Chennai
and drove his car at 70 kmph. At what time Gopalan will overtake Raghavan and
Krishnan?
Options:
a) 1.00pm and 12.20 pm            b) 1.30 pm and 12.10 pm 
c) 1.30 pm and 12.20 pm           d) none of these.
Answer: c) 1.30 pm and 12.20 pm
Solution:
Raghavan and Krishnan would have travelled 50 km and 40 km by the time Gopalan
starts at 11 am.
Gopalan is driving at 70 kmph.
Relative speed – Gopalan with respect to Raghavan = 70 - 50 = 20 kmph
Distance travelled by Raghavan when Gopalan started = 50 km. 
To catch up with Raghavan, time taken by Gopalan = Distance covered by Raghavan
when Gopalan starts / Relative speed of Gopalan with respect to Raghavan = 50/20 = 2
½ hours.  Questions/Articles Extracted From www.CareersValley.com
Page 25
Therefore, he will overtake Raghavan at 11.00 + 2.30 = 1.30 pm.
Relative speed of Gopalan with respect to Krishnan = 30 kmph
Distance travelled by Krishnan when Gopalan started = 40 Km.
Time taken by Gopalan to cross Krishnan = Distance covered by Krishnan when
Gopalan started / Relative speed of Gopalan with respect to Krishnan = 40/30 = 1.33
hours = approximately 1 hour 20 minutes
Gopalan is starting at 11 am. So he will overtake Krishnan at 11 + 1hr 20 min = 12.20
pm

(1) Because the foam itself weathers, the foam would have to be reapplied every four years in order to maintain protection against erosion.
(2) Road cuts similar to the one studied typically show low rates of erosion without the foam.
(3) Studies by the company that produces the material are sometimes unreliable because of conflicts of interest.
(4) The rate of erosion from the road cut in the study was greater then expected based on computer simulation models.

21. The Laysan Rail, an insectivore bird once present on several of the Hawaiian Islands, can no longer be found and is thought to be extinct. Scientist originally thought that a decrease in the amount of ground vegetation available for nesting was responsible for the decline of the bird. However, for the decline that increased competition for food was ultimately responsible for the Latsan Rail's inability to survive.
When of the following would best help to account for the change in the accepted explanation for the Laysan Rail's extinctions?
(1) When attempts were made to relocate the Laysan Rail to other islands, the birds lost the geographical cues that they relied on for finding mating sites.
(2) The vegetation on the Laysan Rail's home island was decimated when rabbits were introduced to the island in the 1910s.
(3) The Laysan Rail builds nests under dense ground cover to protect the eggs.
(4) An increase in the use of pesticide resulted in a decrease in the numbers of flies and moths present in the Laysan Rail's territory.

The author assumes which of the following about the “one-day only” sale merchandise in predicting the effectiveness
of these sale?
(1) The rate of returns when merchandise is new makes this “one day only” sale key to a store profitably.
(2) The defects in the merchandise are not so significant that customers will be unwilling to pay even the sale price.
(3) Too few shoppers purchase merchandise at full retail price.
(4) If these sales become popular, then stores will have to have them more after.

Which of the following, if true, would most seriously weaken the company's conclusion?
(1) Because the foam itself weathers, the foam would have to be reapplied every four years in order to maintain protection against erosion.
(2) Road cuts similar to the one studied typically show low rates of erosion without the foam.
(3) Studies by the company that produces the material are sometimes unreliable because of conflicts of interest.
(4) The rate of erosion from the road cut in the study was greater then expected based on computer simulation models.

However, for the decline that increased competition for food was ultimately responsible for the Latsan Rail's inability to survive.
When of the following would best help to account for the change in the accepted explanation for the Laysan Rail's extinctions?
(1) When attempts were made to relocate the Laysan Rail to other islands, the birds lost the geographical cues that they relied on for finding mating sites.
(2) The vegetation on the Laysan Rail's home island was decimated when rabbits were introduced to the island in the 1910s.
(3) The Laysan Rail builds nests under dense ground cover to protect the eggs.
(4) An increase in the use of pesticide resulted in a decrease in the numbers of flies and moths present in the Laysan Rail's territory.

The author assumes which of the following about the “one-day only” sale merchandise in predicting the effectiveness
of these sale?
(1) The rate of returns when merchandise is new makes this “one day only” sale key to a store profitably.
(2) The defects in the merchandise are not so significant that customers will be unwilling to pay even the sale price.

1)  5 Men are living in a home. The average age of the five men before 5 years was 55.
After P years, one man aged 50 joins with others in the house which makes the average
age 60. Find the value of P.
Options
a) 4        b) 3         c) 2        d) 7
Answer: a) 4
Explanation:
Let the total age of 5 men be X.
Then the average age of 5 men before 5 years = (X - number of years x number of men)
/ number of men = (X - 3x5)/5 = (X-15)/5 = 55
Then X = 55 x 5 + 15 = 290. That is, presently the total age = 290.
After P years, the total age of the 5 men becomes X + 5xP = 290 + 5xP.
One man aged 50 joins with them. Therefore the average becomes (Total age of 5
original men after P years + Age of new man) / Total number of men = (290 + 5P + 50)/
(5+1) = 60
or 5P = 360 - 340 = 20
p = 20/5 = 4
Therefore, 4 years is our required answer.
2) A boy has several colored balls in his bag - 12 white, 15 orange and 25 pink. The
lights are out and it is totally dark. Now, how many balls he must take out to make sure
that he has a pair of each color?
Options
a) 40       b) 42        c) 6        d) 12
Answer: b) 42
Explanation: Questions/Articles Extracted From www.CareersValley.com
Page 5
In this problem, the worst case scenario will be as follows.
Step 1: He picks all of same colored balls of the largest group. The largest group is pink.
Therefore, he will be picking all 25 pink balls first.
Step 2: Then he picks all of same colored balls of the next largest group. The second
largest group is Orange. Therefore, he will be picking 15 orange balls.
Step 3: Now, if he starts picking the remaining balls which are white, he could very well
stop at 2 balls as he would be having a pair of white ball anyway.
Therefore total picks = 25 + 15 + 2 = 42.
Shortcut:
If confused, for these kinds of problems you have to add higher values first + 2, leaving
the least group. Here least group is white.
Therefore our answer will be 25 pink + 15 orange + 2 = 42
Hence the answer is 42.
3)  4 equal aged boys and 6 equal aged girls were regularly attending a guitar class. 22
is the average age of all and 56 is the age of two boys and three girls. After 3 years a
boy is replaced by a new boy aged 15. Now, what will be the average age of boys?
Options
a) 13.5 years      b) 15.4years      c) 16.3 years       d) 14 years
Answer: a) 13.5 years.
Solution:
Let X and Y be the age of a boy and a girl respectively.
Given that 22 is the average age of all.
Then 4X/4 + 6Y/6 = 22
i.e., X + Y = 22 ...eqn1
Also given that, 56 is the age of two boys and three girls.
Then, 2X + 3Y = 56 ...eqn2
Solving the above equations, we get X=10, Y=12.
That is, the age of each boy is 10 and age of each girl is 12.
After 3 years, 1 among 4 boys leaves the group but replaced by a new 15 year old boy. Questions/Articles Extracted From www.CareersValley.com
Page 6
Sum of the ages of 3 left over boys + new boy = Ages of original 3 boys after 3 years +
Age of new boy = 3(X+3) + 15 = 3x13 + 15 = 54 years.
Their average age = Total Age / 4 = 54/4 = 13.5 years.
13.5 Years is our answer.
4) Find the most appropriate meaning for the word ‘Correlate’.
Options:
a. to join        b. to match         c. to refer          d. to fix
Answer: b. to match 
Correlate is to match, observe or compare two or more different things. For example, in
India illiteracy and poverty can be correlated to each other.
5) Find the most appropriate meaning for the word ‘Volatile’.
Options:
a. Oscillate            b. Transient         c. Penetrate             d. Light
Answer: b. Transient.
Transient can be used to refer something that is temporary and volatile.
6) When 8 is subtracted out from two third of X, the result is 25 more than one third of X.
Find the largest prime number which is less than X. 
Options:
a) 113          b) 97           c) 89             d) 131
Answer: b) 97
Solution:
Part-1: To find X.
Below equation can be formed based on the data in question.
(2/3)x X - 8 = 25 + 1/3 x X
(2/3)x X - (1/3)x X = 25+8
X/3 = 33
X=99. Questions/Articles Extracted From www.CareersValley.com
Page 7
Part-2: To find the required prime
97 is the largest prime number which is lesser than 99. Hence 97 is the answer.
7) 6 reduced from 1/5 of a number is 7 reduced from half of the same number. Find the
number.
Options
a)10/3         b)22/3        c)7/3        d)none of these
Answer: a) 10/3
Solution:
X/5 - 6 = X/2 - 7
(X-30)/5 = (X-14)/2
2X-60 = 5X-70
5X-2X = 70-60
3X = 10
X = 10/3
8) Ideal Toy company, New York brought out two models – one rectangle and another
hexagon in shape. The area of the two are same. The base and height of the triangle are
48” and √3” respectively. Find the length of each of the sides of the hexagon.
Options:
a) 2”        b) 4”       c) 24”      d) 8”
Answer: b) 4”
Solution:
Area of triangle = 1/2 x base x height = 1/2 x 48 x √3 = 24√3 sq. inches
Since, the areas of a triangle and hexagon are equal , Area of hexagon = 24√3 sq.
inches ....(1)
If the side of the hexagon is X inches, then its area = (3√3/2 )r
2
 ...(2)
Since equations 1 and 2 equal,
24√3 = (3√3/2 )r

9) Four friends namely Rahul, Ravi, Rajesh and Rohan contested for a dairy milk
chocolate. To decide which friend will get the chocolate they decided to throw two dice.
Every friend was asked to choose a number and if the sum of the numbers on two dice
equals that number, the concerned person will get the chocolate. Rahul's choice was7,
Ravi's choice was 9, Rajesh's choice was 10 and Rohan's choice was 11. Who has the
maximum probability of winning the amount?
Options:
a) Rahul         b) Ravi       c) Rajesh        d) Rohan
Answer: a) Rahul
Solution:
Number 7 will appear more often –(1,6), (2,5), (3,4), (4,3), (6,1), (5,2) --- 6 cases
Number 9 -- (3,6),(6,3), (4,5) (5,4) ---4 cases
For number 10 -- (4,6) ,(6,4) (5,5) ---3 cases
For number 11 -- (5,6),(6,5)...2 cases.
Since number 7 has the maximum chance of appearing, it will have the maximum
probability as well. Hence, Rahul will most probably be the winner.
10)  A man raises sheep and chickens. One fine day, his son wants to count the number
of sheep and chickens. Farmer gives hit as below:
"The average number of legs for each animal is 2 38/57. There are 19 more chickens
than that of sheep." Can you help the son by finding the total number of sheep?
Options:
a) 25         b) 19          c) 17        d) 20
Answer: b) 19 
Solution:
Let the number of sheep be s and the number of chickens be c.
We know every sheep has 4 legs and every chicken has got 2 legs. Questions/Articles Extracted From www.CareersValley.com
Page 9
Total number of legs = 4s + 2c
Average number of legs = Total number of legs / Total number of all animals
= 4s + 2c / (s + c)
It is given that the average = 2 38/57 = 152/57
Therefore 4s + 2c / (s + c) = 152/57
Or 228s + 114c = 152s + 152c
Or 76s = 38c 
Or 2s = c
Also the question states that there are 19 more chickens than that of sheep.
Therefore c - s = 19 ... (1)
Substituting c = 2s in eq 1 we get
2s - s = 19
Or s = 19
(Next 4 questions are of interview type)
11) What is the prime difference between while and Do While Loop?
Answer:
Though while and do-while are loop statements, in Do While it is assured that the
statements within the loop will be executed at least once (even if the condition fails.)
12) What is the difference between a = ++b and a = b++?
Answer:
The first statement a = ++b can be broken down into two statements b = b + 1 followed
by a = b. Hence b will be incremented first and will be assigned to a. Hence values of a
and b will be same at the end.
The second statement a = b++ can be broken down into two statements a = b followed
by b = b + 1. Hence b will be assigned to a. Only after this assignment b will be
incremented. Hence values of a and b will be different at the end.
13) Is it necessary to use register modifier on all compilers irrespective of whether they

15) Which of the following program structure/component/statement is not an example for
the implementation of modularization?
Options 
a) DLL       b) Functions        c) type casting
Answer:
Option c) type casting. DLL and Functions help in modularization of a program while
typecasting just converts from one data type to another.

                                               


1)  5 Men are living in a home. The average age of the five men before 5 years was 55.
After P years, one man aged 50 joins with others in the house which makes the average
age 60. Find the value of P.
Options
a) 4        b) 3         c) 2        d) 7
Answer: a) 4
Explanation:
Let the total age of 5 men be X.
Then the average age of 5 men before 5 years = (X - number of years x number of men)
/ number of men = (X - 3x5)/5 = (X-15)/5 = 55
Then X = 55 x 5 + 15 = 290. That is, presently the total age = 290.
After P years, the total age of the 5 men becomes X + 5xP = 290 + 5xP.
One man aged 50 joins with them. Therefore the average becomes (Total age of 5
original men after P years + Age of new man) / Total number of men = (290 + 5P + 50)/
(5+1) = 60
or 5P = 360 - 340 = 20
p = 20/5 = 4
Therefore, 4 years is our required answer.
2) A boy has several colored balls in his bag - 12 white, 15 orange and 25 pink. The
lights are out and it is totally dark. Now, how many balls he must take out to make sure
that he has a pair of each color?
Options
a) 40       b) 42        c) 6        d) 12
Answer: b) 42
Explanation: Questions/Articles Extracted From www.CareersValley.com
Page 5
In this problem, the worst case scenario will be as follows.
Step 1: He picks all of same colored balls of the largest group. The largest group is pink.
Therefore, he will be picking all 25 pink balls first.
Step 2: Then he picks all of same colored balls of the next largest group. The second
largest group is Orange. Therefore, he will be picking 15 orange balls.
Step 3: Now, if he starts picking the remaining balls which are white, he could very well
stop at 2 balls as he would be having a pair of white ball anyway.
Therefore total picks = 25 + 15 + 2 = 42.
Shortcut:
If confused, for these kinds of problems you have to add higher values first + 2, leaving
the least group. Here least group is white.
Therefore our answer will be 25 pink + 15 orange + 2 = 42
Hence the answer is 42.
3)  4 equal aged boys and 6 equal aged girls were regularly attending a guitar class. 22
is the average age of all and 56 is the age of two boys and three girls. After 3 years a
boy is replaced by a new boy aged 15. Now, what will be the average age of boys?
Options
a) 13.5 years      b) 15.4years      c) 16.3 years       d) 14 years
Answer: a) 13.5 years.
Solution:
Let X and Y be the age of a boy and a girl respectively.
Given that 22 is the average age of all.
Then 4X/4 + 6Y/6 = 22
i.e., X + Y = 22 ...eqn1
Also given that, 56 is the age of two boys and three girls.
Then, 2X + 3Y = 56 ...eqn2
Solving the above equations, we get X=10, Y=12.
That is, the age of each boy is 10 and age of each girl is 12.
After 3 years, 1 among 4 boys leaves the group but replaced by a new 15 year old boy. Questions/Articles Extracted From www.CareersValley.com
Page 6
Sum of the ages of 3 left over boys + new boy = Ages of original 3 boys after 3 years +
Age of new boy = 3(X+3) + 15 = 3x13 + 15 = 54 years.
Their average age = Total Age / 4 = 54/4 = 13.5 years.
13.5 Years is our answer.

10)  A man raises sheep and chickens. One fine day, his son wants to count the number
of sheep and chickens. Farmer gives hit as below:
"The average number of legs for each animal is 2 38/57. There are 19 more chickens
than that of sheep." Can you help the son by finding the total number of sheep?
Options:
a) 25         b) 19          c) 17        d) 20
Answer: b) 19 
Solution:
Let the number of sheep be s and the number of chickens be c.
We know every sheep has 4 legs and every chicken has got 2 legs. Questions/Articles Extracted From www.CareersValley.com
Page 9
Total number of legs = 4s + 2c
Average number of legs = Total number of legs / Total number of all animals
= 4s + 2c / (s + c)
It is given that the average = 2 38/57 = 152/57
Therefore 4s + 2c / (s + c) = 152/57
Or 228s + 114c = 152s + 152c
Or 76s = 38c 
Or 2s = c
Also the question states that there are 19 more chickens than that of sheep.
Therefore c - s = 19 ... (1)
Substituting c = 2s in eq 1 we get

11) What is the prime difference between while and Do While Loop?
Answer:
Though while and do-while are loop statements, in Do While it is assured that the
statements within the loop will be executed at least once (even if the condition fails.)
12) What is the difference between a = ++b and a = b++?
Answer:
The first statement a = ++b can be broken down into two statements b = b + 1 followed
by a = b. Hence b will be incremented first and will be assigned to a. Hence values of a
and b will be same at the end.
The second statement a = b++ can be broken down into two statements a = b followed
by b = b + 1. Hence b will be assigned to a. Only after this assignment b will be
incremented. Hence values of a and b will be different at the end.
