24 minutes.

Step-by-step explanation:

Tap A to fill the cistern in 42 mins

Tap B to fill the cistern in 56 mins

If both the taps are opened together, then

the time taken will be,

According to the question,

1/42+1/56=1/x

1/x=56+42/(42*56)

1/x=98/(42*56)

1/x=49/(42*28)

1/x= 7/(42*4)

1/x=1/24

x=24 min

The time taken by both the tap A and B to fill the cistern is 24 minutes.
