Question

A group of 36 students went for picnic. If 6 students can play with 3 balls, then how many balls are required for the group of 36 students?

Answer 1

For 6 students we need 3 balls.

For 1 students we need $\frac{1}{2}$balls.

Therefore,36 students would need $36\times \frac{1}{2}$ = 18 balls.
