You can put this solution on YOUR website! Assume you mean:
Six taps fill a empty cistern in 8 hours.
6 * 8 = 48 tap-hrs required
How much more time will be taken if two taps go out of order.
let t = time required by the 4 remaining taps
4t = 48
t = 12 hrs required by 4 taps
But it asks how much more time.
12 - 8 = 4 more hrs
You can put this solution on YOUR website! One working alone takes hrs
to fill a cistern
Four of them take hrs
Six of them take hrs
The difference in time is hrs more
