Question

Tap A can fill a tank in 8 hrs, tap B can fill the same tank in 4 hrs and outlet C can empty it in 12 hrs If the two taps and one outlet are opened simultaneously, how many hours will it take to fill the water tank ​

Answer 1

Answer:

Tap A can fill 1 tank in 8 hours

Tap A fills in 1 hour = 1/8 tank

Tap B can empty 1 tank in 12 hours.

Tap B empties in 1 hour= 1/12 tank

Both taps will fill in 1 hour = 1/8 - 1/12

3- 2 / 24 = 1/24

Hence, the tank will be filled completely in 24 hours
