    INFOSYS-Placement Paper-11 June 2006-Chennai

    Here are the questions that appeared in the test. I tried to give the exact words from the test & I think I did well. Also I had given detail answers.

    Q.1) Dr. Watson has 5 nephews. After he died he mentioned in his will that each of his brother's sons should get money according to their ages. The difference between each son is Rs. 20 & youngest son got least money. Total money to be shared is 1000. How much youngest son will get?

    Ans:
    Let the third i.e. middle son will get Rs. x then youngest son will get Rs. x-40.
    => Adding their shares = 1000
    => (x-40) + (x-20) + x + (x+20) + (x+40) = 1000
    => x = 200
    => x - 40 = 160
    => Youngest son will get Rs.160



    Q.2) In a party there r total 1275 handshakes assuming each person did handshake with other fellow. How many people attended the party?

    Ans:
    Let number of people attended the party = x then
    Number of handshakes =xC2 = 1275
    => x * (x - 1) = 1275
    2 * 1
    => x2 - x - 2550 =0
    => (x - 51)(x + 50) = 0
    => x cannot be negative
    => x = Number of people attended party = 51



    Q.3) If one fifth of a hive of bees flew to the rose flower, one third flew to the lotus flower, three times the difference of these two numbers flew to slandbara & one bee continued to fly about, attracted on each side by the fragrant of ketaki & malati, what was the total number of bees?

    Ans:
    X + X + 3( X - X ) +1 = X
    3 5 3 5

    => X = 15 = Number of bees.



    Q.4) Due to some defect in our elevator, I was climbing down the staircase. I had climbed down just 7 steps when I saw professor Zorkoski on the ground floor. Continuing to walk down, I greeted him & I was surprised to see that when I was yet to get down 4 steps to reach the ground floor, professor had already finished the climbing up 2 steps for every 1 of mine. How many steps did the staircase have?

    Ans:
    7 X 4
    |-------------- |------------------|----------------|

    From figure, equation becomes : 7 + X + 4 = 2X

    => X = 11

    => Total number of steps = 7 + 11 + 4 = 22



    Q.5) Complete the following series:
    a) 3, 6, 13, 26, 33, 66, ?

    Ans:
    3 * 2 = 6
    6 + 7 = 13
    13 * 2 = 26
    26 + 7 = 33
    33 * 2 = 66
    66 + 7 = 73
    73 * 2 = 146
    Series : 3, 6, 13, 26, 33, 66, 76, 146

    b) 364, 361, 19, 16, 4, 1, ?

    Ans:
    364 - 3 = 361
    O(364) = 19
    19 - 3 = 16
    O(16) = 4
    4 - 3 = 1
    O(1) = 1
    1 - 3 = -2

    Series: 364, 361, 19, 16, 4, 1, 1, -2


    Q.6) A man was asked to meet a lady lawyer who had a good logical skill. Today is Saturday. A man wanted her appointment. She called her three days after the day before the day after tomorrow. What is the appointment day?

    Ans:
    Today = Saturday
    Day after tomorrow = Monday
    Day before the day after tomorrow = Sunday
    Three days after the day before the day after the tomorrow = Wednesday
    Therefore, Appointment day is Wednesday.



    Q.7) Find the values of X, Y, Z & B using following equations. Substitute values from 0 to 9 without repetition.

    X Y G X Y G
    + -
    A B A B
    -------------- -------------
    C D E F B G A

    Ans: 9 4 5 9 4 5
    + -
    7 8 7 8
    --------------------- -------------------
    0 2 3 8 6 7



    Q. 8) Somebody asked a wizard, Alchimiro about his age. He answered that he is still young according to age of wizards. Let me tell u, I m thrice my son's age & my father's age is 40 more than twice of my age. Total of our ages is 1240 years. What is the age of wizard?

    Ans:

    Let wizard's son age = X then wizard's age = 3X & his father's age = (6X+40)
    => X + 3X + 6X + 40 = 1240
    => X = 120

    Wizard's age = 360 years



    Q.9) This was 8 marks question regarding the committees of 5 juniors & 4 seniors they have to form 3 committees. Some conditions had given & based upon that we have to answer 4 questions. I solved it last. Sorry for not remembering the question.



    Q.10) A man enquires a person about the past 5 day's temperature at noon in that region. The other replies that he doesn't remember the actual figures but there was a different temperature on each day & their product gives 12. Assuming the temperature to the nearest degree what are the temperatures on the five days in Celsius?

    Ans: Temperatures on 5 consecutive days are: -2, -1, 1, 2, 3 in degree Celsius.



    HR interview was cool. They didn't ask me to explain myself, a most imp question. Being a chemical engineer they keep asking me why you are not interested in chemical industry & what u did in last 1 year. I explained them all truly & they look convinced. So my advice is be true to them, they are among top mind readers. They will easily catch your bluffs. They asked me which concept from computer u like most. I told them about OOPS & explained it. They also asked me how u will adjust within a team. Such HR questions. Then they had given me a simple puzzle.
    Well this is all about my Infosys experience. I was selected, now working at banglore
