there are 600 pupils in school. the ratio of boys to girls is 3:5. How many girls a d how many boys are in this school?

Step-by-step explanation:

Here,

No. Of total =600

Let,

no. Of boy=3x

no. Of girls = 5x

By the question,

Number of boys and number oof girls =600

or,3x +5x=600

or, 8x =600

or, x= 600/8

or, x= 75

Again,

No. Of boys =3x

Or, 3 * 75

=225

No. Of girls = 5x

Or, 5 * 75

= 375

72 is the answer to this problem
