    Hi Friends,

    I am M. Swarna kumar  Bapatla Engineering College. TCS requitment is conducted on 27-11-10 to 29-11-10.

    It consis of 4 rounds.

    1. Written test
    2. Technical round
    3. MR round
    4. HR round

    In written test the questions is as follows it have total 35 questions

    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 h ow many 5 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) 500 
    d) 625
    Ans: d

    2) A circular dartboard of radius 1 foot is at a distance of 20 feet from you. You throw a dart at it and it hits the dartboard at some point Q in the circle.

    Ans: 0.25


    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

    Ans: 0

    Ans: D

    12) 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?

    13) On planet zorba, a solar blast has melted the ice caps on its equator. 8 years after the ice melts, tiny plantoids called echina start growing on the rocks. echina grows in the form of a circle and the relationship between the diameter of this circle and the age of echina is given by the formula
    d = 4 * ? (t - 8) for t ? 8

    Where the represents the diameter in mm and t the number of years since the solar blast. Jagan recorded the radius of some echina at a particular spot as 8mm. How many years back did the solar blast occur?

    Just substitute values then you get ans

    14) 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
