Question

3 alike taps can fill tanks in 2 hours determine the time in which the tank can be filled if only 2 of them are opened​

Answer 1

Answer:

3 hours

Step-by-step explanation:

Let the time taken by one tap to fill the tank be x

So, tank filled in 1 hour woulod be 1/x

3 alike taps are working

So, in 1 hour

   1/x + 1/x + 1/x = 1/2

   x = 6

So, one tap can fill the tank in 6 hours

If two taps are open let the time taken be x

  x/6 + x/6 = 1

  x = 3

So. 2 taps can fill the tank in 3 hours
