Suppose pipe A alone takes x hours to fill the tank.
Then, pipes B and C will take x/2 and x/4 hours respectively to fill the tank.
∴1/x + 2/x + 4/x = 1/5
⇒7/x = 1/5
⇒x = 35hours
Then, pipes B and C will take x/2 and x/4 hours respectively to fill the tank.
∴1/x + 2/x + 4/x = 1/5
⇒7/x = 1/5
⇒x = 35hours
