Question:

Tap A can fill a tank in 6 hours and tap B can empty the same tank in 10 hours. If both taps are opened together, then how much time (in hours) will be taken to fill the tank?

Options:

15

18

20

16

Correct Answer:

15

Explanation:

A+ = 6 hrs, B- = 10 hrs,

⇒ Time required by A + B to completely fill the tank = \(\frac{30}{5-3}\) = \(\frac{30}{2}\) = 15 hrs.
