    Hey! Pretty stranger 😀

    AsnwEr:

    • Number of girls in class = 15

    GivEn:

    • The ratio of no. of boys to no. of girls in a class is 4:5.
    • Number of boys in class = 12

    To find:

    • Number of girls in class?

    Solution:

    ☯ Let number of girls be x.

    Given that,

    • The ratio of no. of boys to no. of girls in a class is 4:5.

    Therefore,

    → 12/x = 4/5

    → x = 12 × 5/4

    → x = 60/4

    → x = 15

    ∴ Hence, number of girls in a class is 15.
