Show Answer

Correct Answer: (2)

Solution: (2)

Students who participate in dance :

Class VII $\Rightarrow \frac{400 \times 10}{100}=40$

Class IX $\Rightarrow \frac{250 \times 10}{100}=25$

Their sum $=40+25=65$

Students who participate in play :

Class VI $\Rightarrow \frac{500 \times 8}{100}=40$

Class VIII $\Rightarrow \frac{360 \times 10}{100}=36$

Their sum $=40+36=76$

Required ratio $=65: 76$
