Question

The boys and girls in a school are in ratio 7:8. If total strength of school be 1050. Find number of boys
and girls.​

Answer 1

Answer:

Ratio of boys and girls =7:8

let no. of boys be 7x

and no. of girls be 8x

7x+8x =1050

15x =1050

x = 1050/15

x =70

no. of boys =70×7

no. of girls =70×8

Answer 2

Answer:

Step-by-step explanation:

Let the number of boys be 7x and the number of girls be 8x.

Total strength is 7x + 8x =15x

Given that the total strength is 1050,

15x = 1050

Dividing both sides by 15, we have

x = 1050/15 = 70

Number of boys = 7 times 70 = 490

Number of girls = 8 times 70 = 560

Verification : 490 + 560 = 1050
