It consists of 3 rounds.

1. Written test 2. Technical and Managerial Round 3. HR round

* In our college "231" members are attended; out of which"122" are cleared written test. * In these 122 around 93 are cleared Technical and Managerial Round. * In those 93 all cleared HR Round.

All questions are Aptitude questions, no Verbal, no Passages etc. Only Aptitude based on blood relations, percentages, profit-loss and Probability etc.

Ans: d

7. 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 9/10 of winning the game. What is the probability that Paul will correctly pick the winner of the Ghana-Bolivia game? a) 0.9 b) 0.62 c) 0.79 d) 0.82 Ans: 0.82

8. Alok and Bhanu play the following min-max game. Given the expression N = 9 + X + Y - Z Where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu 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 a) 27 b) 0.0 c) 20 d) 18 Ans: 20

9. Alok is attending a workshop "How to do more with less" and today's theme is working with fewer digits. The speakers discuss how a lot of miraculous mathematics can be achieved if mankind (as well as woman kind) had only worked with fewer digits. The problem posed at the end of the workshop is how many 4 digit numbers can be formed using the digits 1, 2, 3, 4, 5 (but with repetition) that are divisible by 4? Can you help Alok find the answer? a) 375 b) 3125 c) 125 d) 625 Ans: c

10. 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 ubsequent 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 Alice has no winning strategy.

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. Ans c)

11. 12 people {a1, a2, ..., a12} meet and shake hands in a circular fashion. In other words, there are totally 36 handshakes involving the pairs, {a1, a2}, {a2, a3}, ..., {a11, a12}, {a12, 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) 6 b) 4 c) 12 d) 3 Ans: b

12) Given a collection of points P in the plane , a 1-set is a point in P that can be separated from the rest by a line, .i.e the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The minimum value of n1(P) over all configurations P of 5 points in the plane in general position (.i.e no three points in P lie on a line) is

a) 3 b) 5 c) 2 Ans: b
