If total member is 16

Then boys are

5

3

×16=9.6

Then girls are

5

2

×16=6.40

Number of members can't be a fraction.

(B) Given ratio is 3:2

Then3+2=5

If total member is 18

Then boys are

5

3

×18=10.8

Then girls are

5

2

These are friction that member not 18.

Number of members can't be a fraction.

(C) Given ratio is 3:2

Then 3+2=5

If total member is 24

5

3

×24=14.40

Then girls are

5
