A Large Tanker Can Be Filled By Two Pipes A And B In 60 And 40 Minutes Respectively. How Many Minutes Will It Take To Fill The Tanker From Empty State If B Is Used For Half The Time And A And B Fill It Together For The Other Half? |
|
Answer» Part FILLED by (A + B) in 1 minute = (1/60 + 1/40) = 1/24 SUPPOSE the TANK is filled in x minutes. Then, x/2(1/24 + 1/40) = 1 x/2 * 1/15 = 1 => x = 30 min. Part filled by (A + B) in 1 minute = (1/60 + 1/40) = 1/24 Suppose the tank is filled in x minutes. Then, x/2(1/24 + 1/40) = 1 x/2 * 1/15 = 1 => x = 30 min. |
