Answer 2

Step-by-step explanation:

Total strength of the school= 1120

Let the number of boys be 4x and number of girls be 3x.

Total strength of the school= number of boys + number of girls

1120=4x+3x

1120=7x

1120÷ 7= x

160=x

As, x= 160.

Therefore, 4x= 4 × 160= 640 boys

and 3x= 3 × 160=480 girls

Thus, there are 640 boys and 480 girls in the school.
