Solution

The correct option is A $$35$$
$$5$$ person maintained for $$20$$ days with Rs. $$2,480.$$

Then, $$1$$ person maintained at $$\dfrac{2480}{20\times5}=\dfrac{2480}{100}$$$$=$$Rs. $$ 24.80$$ /person/day

So, the maintenance of $$8$$ persons $$ =24.80\times 8=198.40$$ /day.

So, the number of days Rs $$6944$$ can be maintained $$8$$ person will be

$$\dfrac{6944}{198.40}=35 $$  days
