Question

hi pls answer this one...\


ii) 6 taps with the same rate of flow can fill a tank in 18 minutes. If two taps are closed, how long will the remaining taps take to fill the tank?

Answer 1

Answer:

I think it is 12 minutes.

Answer 2

Answer:

Given that,

8 taps of the same size fill a tank in 27 minutes.

So, 1 tap can fill the tank in 7×27=189 minutes

If two taps go out of order, then the remaining taps =7−2=5

Therefore, Time taken  by 6 taps to fill the tank =6÷289=0.0264550265
