Show Answer

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 $=\frac{40+24+36+30}{4}$ $=\frac{130}{4}=\frac{65}{2}=32 \frac{1}{2}$
