| Re: TCS Placement Exam Sample Question Paper
Here I am providing you Sample Question Papers for preparation of TCS Placement Exam while pursuing B.Tech in CS. Sample Question Papers for TCS Placement Exam: 1) 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 coins 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. 2) 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) 1/9 b) 4/9 c) 5/9 d) 2/3 3) 36 people {a1, a2, …, a36} meet and shake hands in a circular fashion. In other words, there are totally 36 handshakes involving the pairs, {a1, a2}, {a2, a3}, …, {a35, a36}, {a36, a1}. Then size of the smallest set of people such that the rest have shaken hands with at least one person in the set is a) 12 b) 11 c) 13 d) 18 4) After the typist writes 12 letters and addresses 12 envelopes, she inserts the letters randomly into the envelopes (1 letter per envelope). What is the probability that exactly 1 letter is inserted in an improper envelope? a) 1/12 b) 0 c) 12/212 d) 11/12 5) A can do a work in 15 days and B in 20 days. If they work on it together for 4 days, then the fraction of the work that is left is: a) 1/4 b) 1/10 c) 7/15 d) 8/15 6) If VXUPLVH is written as SURMISE, what is SHDVD ? 7) If DDMUQZM is coded as CENTRAL then RBDJK can be coded as ——— 8) In the word ECONOMETRICS, if the first and second , third and forth ,forth and fifth, fifth and sixth words are interchanged up to the last letter, what would be the tenth letter from right? 9) Find the result of the following __expression if, M denotes modulus operation, R denotes round-off, T denotes truncation: M(373,5)+R(3.4)+T(7.7)+R(5.8) 0) Find the missing number in the series: 2, 5, __ , 19 , 37, 75.
