Answer 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.
