First Round Written Test: Aptitude Test
Written Test 35 Questions
Time : 80 Minutes
There
was 35 Simple Aptitude
Questions (but lengthy) with
Negative Marking (1 Mark For
3 Wrong Answers) You have to
attempt 35 question in 80
minute.
In the aptitude test
each & every question in the
aptitude test was from
previous paper as per the new
pattern. I attempt 30
uestions which was correct.
You can get through if you
prepared with previous papers
and having a little presence
of mind. I m giving u the
questions with solution of
some of them.
1. (1/2) of a number is 3
more than the (1/6) of the
same number?
a) 6
b)7
c)8
d)9
Solution:
Let the number be x,
((1/2)*x)=3+(1/6)*x,
Then solve x
2. There are two water tanks
A and B, A is much smaller
than B. While water fills at
the rate of 1 liter every
hour in A, it gets filled up
like, 10, 20, 40, 80, 160 in
tank B. (At the end of first
hour, B has 10 liters, second
hour it has 20 liters and so
on). If tank B is 1/32 filled
of the 21 hours, what is
total duration of hours
required to fill it
completely?
a) 26
B)25
c)5
d)27
Solution: for every hour
water in tank in B is doubled, Let the duration to fill the
tank B is x hours. x/32 part of water in tank of
B is filled in 21 hours, Next hour it is doubled so,
2*(x/32) part i.e (x/16)
part is filled in 22 hours, Similarly (x/8)th part in 23
hours,(x/4)th part is filled
in 24 hours, (x/2)th part is filled in 25
hours, (x)th part is filled
in 26 hours So answer is 26 hours.
3. 6 persons standing in
queue with different age
group, after two years their
average age will be 43 and
seventh person joined with
them. Hence the current
average age has become 45.
Find the age of seventh
person?
a) 43
b) 69
c) 52
d) 31
Solution:
Total age of 6 persons is x
hours, after two years total
age of 6 persons is x+12 Average age of 6 persons is
after two years is 43 So (x+12)/6=43,then solve x,
After 7th person is added
then (x+7th person age)/7=45 So we will get 7th person age
easily
4.In the reading room of a
library, there are 23 reading
spots. Each reading spot
consists of a round table
with 9 chairs placed around
it. There are some readers
such that in each occupied
reading spot there are
different numbers of readers.
If in all there are 36
readers, how many reading
spots do not have even a
single reader?
a) 8
b) none
c) 16
d) 15
Solution: 23 reading spots,
Each reading spot consists of
9 chairs placed around it so
There are some readers such
that in each occupied reading
spot there are different
numbers of readers. For each table different no
of persons are sat,so for
first table 1 person is sit,
2nd table 2 persons are sit 36
readers means(1+2+3+4+5+6+7+8
so 8 tables are filled so 23-
8=15 reading spots does not
have single reader.
5. A man jogs at 6 mph over a
certain journey and walks
over the same route at 4 mph.
What is his average speed for
the journey?
a) 2.4 mph
b) 4.8 mph
c) 4
mph
d) 5 mph
Solution: Average speed=(2*x*
y)/(x+y)
6. Susan made a block with
small cubes of 8 cubic cm
volume to make a block ,3
small cubes long, 9 small
cubes wide and 5 small cubes
deep. She realizes that she
has used more small cubes
than she really needed. She
realized that she could have
glued a fewer number of cubes
together to lock like a block
with same dimensions, if it
were made hollow. What is the
minimum number of cubes that
she needs to make the block?
a) 114
b) 135
c) 21
d) 71
Solution: ,((3*9*5))-((3-2)*(
9-2)*(5-2)) so answer is 114.
7. ((4x+3y)+(5x+9y))/(5x+5y) =
? as (x/2y) = 2
a)8
b) none
c)16

9. A toy train produces 10
different sounds when it
moves around a circular toy
track of radius 5 m at 10 m
per min. However, the toy
train is defective and it now
produces only 2 different
tunes at random. What are the
odds that the train produces
for consecutive music tones
of the same type?
a) 1 in 16
B) 1 in 4
c) 1 in
8
d) 1 in 32
Solution: Initially it
produces 10 sounds and the
defect came and now it
produces only 2 different
sounds and consecutively so
there are totally 2 sounds
and we have to select on
sound and the probability is ½
and it produces the same
sound concecutively for 2
times so the probability
becomes ½*1/2 ie ¼
10. A triangle is made from a
rope. The sides of the
triangle are 25 cm, 11 cm and
31 cm. What will be the area
of the square made from the
same rope?
a) 280.5625
b) 240.5625
c)
280.125
d) 240
Solution: add all sides 25+11+
31 to get rope length rope
length =67,rope is made in to
as square So side of square is 67/4=16.
75 and so area is 16.75*16.75=
280.5625

30. Alice and Bob play the
following coins-on-a-stack
game. 20 coins are stacked
one above the other. One of
them is a special (gold) coin
and the rest are ordinary
coins. The goal is to bring
the gold coin to the top by
repeatedly moving the topmost
coin to another position in
the stack.Alice starts and
the players take turns. A
turn consists of moving the
coin on the top to a position
i below the top coin (0 = i =
20). We will call this an i-
move (thus a 0-move implies
doing nothing). The proviso
is that an i-move cannot be
repeated; for example once a
player makes a 2-move, on
subsequent turns neither
player can make a 2-move. If
the gold coin happens to be
on top when it's a player's
turn then the player wins the
game. Initially, the gold
coinis the third coin from
the top. Then
a) In order to win, Alice's
first move should be a 1-move.
b) In order to win, Alice's
first move should be a 0-move.
c) In order to win, Alice's
first move can be a 0-move or
a 1-move.
d) Alice has no winning
strategy.
