Question

the ratio of boys and girls in school is 4: 3 if the total strength of the school is 560 find the number of boys and girls in the school.​

Answer 1

Answer:

Boys=320; Girls=240

Step-by-step explanation:

let the no. of boys be 4x and no. of girls be 3x.

( Since ratio is 4:3)

So, 4x+ 3x= 560

therefore, x= 80

Hence , Boys =4x = 320

and Girls =3x= 240

Answer 2

Step-by-step explanation:

4x+3x = 560

7x = 560

x = 560/7

x = 80

Number of boy's = 4x = 4×80 = 320

& Number of girl's = 3x = 3×80 = 240
