    boys 3 and girls 7

    Step-by-step explanation:

    total students=10

    let x be the number of boys

    girls is 4 more than the boys so

    number of girls is 4+x

    as per given data

    4+x+x =10

    4+2x=10

    2x=10-4

    2x=6

    x=6/2

    x=3

    therfore number of boys is 3 and girls is 7

    Answer:

    Step-by-step explanation:

    Formulation:

    Let the number of girls is x and the number of boys is y. It is given that a total of ten students took part in the quiz.

    ∴ Number of girls + Number of boys =10

    i.e., x+y=10

    It is also given that the number of girls is 4 more than the number of boys.

    ∴ Number of girls = Number of boys +4

    i.e., x=y+4

    or, x−y=4

    Algebraic Representation:  

    Thus, the algebraic representation of the given situation is

    x+y=10       (i)

    x−y=4         (ii)
