Answer:
GIVEN THAT
TAP A takes 30 mins
TAP B takes 45 mins
work done in 1 minute by each tap
= tap A = 1/30
= tap B = 1/45
work done by both taps together in 1 min = 1/30 + 1/45
= 3/90 + 2/90
= 5/90
= 1/18
so total work done by taps together = 18 min
so, the both taps together take 18min to fill the tank
