Answer» ? Time TAKEN by first pipe to fill the tank = 6 hours ∴ In one HOUR the First pipe can fill tank (by volume) = (1/6) ? Time taken by Second pipe to fill the tank = 8 hours ∴ In one hour the Second pipe can fill tank (by volume) = (1/8) ⇒ If operated together the two pipes can fill tank (by volume) in one hour = (1/6) + (1/8) = 14/48 = 7/24 ⇒ The Tank will be FILLED in time = 24/7 HRS $(3\frac{3}{7})$ hours |
