    INFOSYS WRITTEN TEST(SOLUTIONS) 14 th JULY,2006  MAIT, 

    Answers:

     

    Ans 1) 338..no explanations

     

    Ans 2) 30 minutes

    Tap 1 fills 1/10 tub in a minute

    Tap2 fills 1/15 tub in a minute

    In one minute, tub filled by two taps = 1/10 + 1/15

    Drainage pipe empties 2/15 tub in a minute(1/7.5)

     

    Total tub filled in one minute= 1/10+1/15-(2/15)=1/30

    So tub takes 30 minutes to fill.

     

    Ans 3) Annie?s foot prints

    I solved this question by hit and trail.

    I first took Annie as truthful, then Fanny as truthful and then Danny as truthful and the answer was easily derivable?.

     

    Ans4)  (a) 30

    Separate even position terms and odd position terms, u will get

    Even position terms: 4,8,12,16??.(multiples of four)

    Odd position terms: 2,6,12,20?..(the difference between consecutive terms is in A.P?.

                                                                Like 2+4=6

                                                                        6+6=12

                                                                       12+8=20

                                                                thus,20+10=30)          

                (b) 73

     

    the series goes like this:

    3

    3*2=6

    6+7=13

    13*2=26

    26+7=33

    33*2=66

    66+7=73

    That is, multiply by two and add 7 alternatively.

     

    Ans5) (a)8

                (b)12

                (c)6

                (d)1

    Pure analytical question, no explanation required.

     

    Ans 6) 45 kmph

    Let speed of car be x kmph

    Let at first he sees digits as ?ab??that is the value of number is: 10a+b

    After traveling for one hour, he sees the number as ?ba??thus its value is 10b+a

    After traveling another hour,he sees the number as ?a0b??thus value is 100a+b

     

    Now,

    10a+b+x=10b+a..which gives x=9b-9a

    10b+a+x=100a+b..which gives x=99a-9b

     

    Equating we get,

    b=6a

    since ?a? and ?b? are digits, a=1 and b=6 and thus x=45

     

    Ans7)84 years

     

    Let the final age of man be ?x? years

    He spent x/6 in childhood

    He spent x/12 in youth

    He spent x/7 as bachelor

    and 5 years as bachelor

    At the time of birth of his son, his age was: x/6+x/12+x/7+5

    His son was of age x/2 when son died

    At the death of his son, man?s age: x/6+x/12+x/7+5+x/2

    According to question

    x/6+x/12+x/7+5+x/2=x-4

    solve for x

     

    Ans 8)3 girls and 4 boys in family

     

    let the number of  girls in family be x

    Thus, the number of  boys in family =x+1

     

    Since each girl have twice the number of bros than sis,thus

    No of sis for a girl=x-1

    No of bros for a girl=x+1

    And, thus x+1=2(x-1)

    Gives x=3

     

    Ans9) 121

     

    LCM of 2,3,4,5,6 is 60

    Since they all leave remainder 1, the number should be 61,

    But 61 is not divisible by 11

     

    Next higher number divisible by 2,3,4,5,6 is 120 and adding the remainder becomes 121 which is divisible by 11 as well satisfying all the conditions

     

     

    Ans 10)

    A-Manager

    B-Cashier

    C-Floorwalker

    D-Clerk

    E-Buyer

     

    Pure analytical question, no explanations
