Question

The ratio of the number of boy scouts to the number of girl guides is 8 : 7. If there are 675 boy scouts and girl guides in all, find the number of girl guides.

Answer 1

Answer:

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

according to question,

8x + 7x = 675

or 15x = 675

or x = 675/15

or x = 45

Therefore, number of girls guides=7x=7×45=315
