Hello friends

I want to share my experience with you on the way of TCS.

The question paper of TCS is as:

There is only one section which consists of aptitude questions with (1,-1/3) marking scheme.

1) A circular board of radius 1 foot is at a distance of 20 feet from you. You throw a ball at it and it hits the board at some point Q in the circle. What is the probability that Q is closer to the centre of the circle than the periphery?

A.0.75 B.1 C. 0.5 D. 0.25

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

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

4) For the FIFA world cup, Paul the octopus has been predicting the winner of each match with amazing success. It is rumored that in a match between 2 teams A and B, Paul picks A with the same probability as A’s chances of winning. Let’s assume such rumors to be true and that in a match between Ghana and Bolivia, Ghana the stronger team has a probability of 2/3 of winning the game. What is the probability that Paul will correctly pick the winner of
the Ghana-Bolivia game?
A.4/9 B. 2/3 C. 1/9 D. 5/9

5) The citizens of planet nigiet are 7 fingered and have thus developed their decimal system in base 8. Acertain street in nigiet contains 1000 (in base 8 buildings numbered 1 to 1000. How many 6s are used in numbering these buildings when represented in base 10 ?
A.256 B.147 C.192 D. None of these

6) 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 imove 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 coin is the third coin from the top. Then

A. In order to win, Alice’s first move should be a 0-move.
B.In order to win, Alice’s first move should be a 1-move.
C.Alice has no winning strategy.
D. In order to win, Alice’s first move can be a 0-move or a 1-move.

8) A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the hare in the other. The hare starts after the tortoise has covered 1/5 of its distance and that too leisurely.The hare and tortoise meet when the hare has covered only 1/8 of the distance. By what factor should the hare increase its speed so as to tie the race?
A.40 B. 37 C..80 D.8 5

9) There are two boxes, one containing 10 red balls and the other containing 10 green balls.
