3* 40/15 >= 8
IMO B 9

Can someone please give another approach?

If Basses are 9 means that:

3x = 9

x = 3

And then 15x will be 45, which is more than the singers required.

Equate 15x with 40;

15x=40
X=8/3

Since x cannot be a decimal and must be a whole number and a multiple of 3, the least possible number is 9.

Press kudos if that helped
