Answer 2

Answer:

A in 40 days and B in 24 days.

Step-by-step explanation:

lets assum that swimming pool has 15 subparts. A and B together can fill one subpart in 1 day so they filled 12 subparts in 12 days.

Rest 3 subparts are filled by tap A in 8 days. so tap A requires 40 days to fullfill all 15 subparts of swimming pool.

now when both taps are on

(1/40)+(1/D)=1/15 where D is days taken by tap B to fill All 15 parts.

D=24 days
