Answer 1

Answer:

Tap A can fill tank in 12 hrs

Tap B can fill tank in 16 hrs

Tap C can empty the tank in -8hrs

Tap A's 1 hr work = 1/12

Tap B's 1 hr work = 1/16

Tap C's 1 hr work = -1/8

Tap (A+B+C)'s 1 hr work = 1/12 + 1/16 - 1/8

= 7-6/48 = 1/48 = 48 hours

Hence, all the taps will take 48 hrs to fill the tank.

hope it help you!
