    A college consisting of a total of 1560 students has males and females in the ratio of 7 : 5 respectively. All the students are enrolled in different types of streams, viz., Maths , Physics and Commerce. One-fifth of the males are enrolled in only Physics stream. Twenty per cent of the females are enrolled in only Commerce stream. Ten percent of the males are enrolled in only Maths stream. Twenty-four per cent of the females are enrolled in both Maths and Physics stream together. The number of females enrolled in only Maths stream is two hundred per cent of the males enrolled in the same. One-thirteenth of the males are enrolled in all the three streams together. The respective ratio of males enrolled in Physics and Commerce stream together to the females enrolled in the same is 2 : 1 respectively. Ten per cent of the females are enrolled in only Physics stream whereas eight per cent of the females are enrolled in both Physics and Commerce stream together. The remaining females are enrolled in all the three streams together. The number of males enrolled in Maths and Physics stream together is fifty per cent of the number of females enrolled in the same. The remaining boys are enrolled in only Commerce stream.

    36.66
    35.71
    34.50
    None of these
    Option C

    452
    455
    465
    434
    None of these
    Option D
    Required number=78+182+70+104

  6. Read the given information and answer the following questions:

    The number of male passengers who boarded Rajdhani express is 175% of the number of female passengers who boarded the same train. The ratio of the number of passengers who like Coldrink , Juice and Water is 61 : 67 : 37. Each passenger likes only one item out of three. The number of male passengers who like Coldrink is 28% more than the male passengers who like Juice. Ratio of the number of male passengers who like Water and the male passengers who like Coldrink is 5:9. Number of female passengers who like Juice is 320 and is 53⅓% of the number of total female passengers. The ratio of number of female passengers who like Coldrink and Water is 4 : 3.

    Find the difference between the male passengers who like Water and female passengers who like Coldrink?
    90
    100
    75
    80
    None of these
    Option A
    Let the number of female passengers be 100x.
    Then ,number of male passengers=100x*175/100=175x
    The number of female passengers who like Juice=100x*160/300=320
    x=6
    Number of total female passengers=6*100=600
    Number of total male passengers=175*6=1050
    Number of male passengers who like Coldrink=1650*61/165=610
    Number of passengers who like juice=670
    Number of passengers who like Water=1650-(610+670)=370
    Number of female who like Coldrinnk=(600-320)**4/7=160
    Number of male who like Water=120
    Let number of male passengers who like Juice be 7y.
    Then,number of male passengers who like Coldrink=7y*9/7=9y
    therefore,7y+9y+5y=1050
    y=50

     


  7. The number of female passengers who like Coldrink and Water together is how much percent more or less than the number of male passengers who like Juice?
    25%
    20%
    30%
    15%
    None of these
