  1. Answer:

    48 STUDENTS ARE IN CLASS.

    Step-by-step explanation:

    LET,

    THE NUMBER OF BOYS = 7X

    THE NUMBER OF GIRLS = 5X

    ACCORDING TO THE QUESTION,

    7X = 5X + 8

    2X = 8

    X = 4

    THEREFORE,

    THE NUMBER OF BOYS = 7X = 7 × 4 = 28.

    THE NUMBER OF GIRLS = 5X = 5 × 4 = 20.

    HENCE,

    TOTAL STRENGTH OF CLASS = 28 + 20 = 48.

    THANKYOU.
