Correct Answer: 348.(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 $=65: 76$
