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.

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

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

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.
