  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?
