Correct Answer: (1)
Solution: (1) Students who participate in play :
Class VI $\Rightarrow \quad \frac{500 \times 8}{100}=40$
Class VII $\Rightarrow \frac{400 \times 6}{100}=24$
Class VIII $\Rightarrow 36$ Class IX $\Rightarrow \frac{250 \times 12}{100}=30$
$\therefore$ Required average
$=\frac{40+24+36+30}{4}$
$=\frac{130}{4}=\frac{65}{2}=32 \frac{1}{2}$
