Answer 1

Answer:

In one hour tap A can fill 1/4 of tank.

In one hour tap B can emply 1/6 of tank.

In one hour tap A and tap B (both open) can fill 1/4 - 1/6 of the tank OR 1/12 of the tank

Thus time taken to fill 1/12 of tank = 1 hour

Therefore,

Time taken to fill full (1) tank = 1 X 1 divided by 1/12

OR 12 hours
