TCS changed their aptitude test patterns but still questions comes from old pattern...
So, all 70 questions pattern I posted on my blog so that my readers should prepare for both old as well as new pattern...
Pattern 1:
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.
(1/3) of a number is 3 more than the (1/6) of the same number?
a) 6 b)16 c)18 d)21
3. (1/3)
of a number is 6 more than the (1/6) of the same number?
a) 6 b)18 c)36 d)24
4.
(2/3) of a number is 4 more than the (1/6) of the same number?
a) 6 b)8 c)36 d)24
5.
(1/3) of a number is 5 more than the (1/6) of the same number?
a) 6 b)36 c)30 d)72
Pattern 2:
1. 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.
2.
There are two pipes A and B. If A filled 10 liters in an hour, B can fill 20
liters in same time. Likewise B can fill 10, 20, 40, 80, 160. If B filled in
1/16 of a tank in 3 hours, how much time will it take to fill the tank
completely?
a) 9 B) 8 c) 7 d) 6
3.
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. 1/8 th of the tank B is filled in 22 hours. What is the time
to fill the tank fully?
a) 26 B) 25 c) 5 d) 27
4. A
tank is filled with water. In first hour 10 liters, second hours 20 liters, and
third hour 40 liters and so on. If time taken to fill ¼ of the tank if 5 hours.
What is the time taken to fill up the tank?
a) 5 B) 8 c) 7 d) 12.5
5. If a
tank A can be filled within 10 hours and tank B can be filled ¼ in 19 hours
then, what is the time taken to fill up the tank completely?

Pattern 3:
1. 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

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

would like to minimize it. Towards this end, Alok chooses a single digit number
and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then
chooses the next value and Bhanu, the variable to substitute the value. Finally
Alok proposes the value for the remaining variable. Assuming both play to their
optimal strategies, the value of N at the end of the game would be

Q7. 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.
