Answer» Correct Answer - Option 5 : Quantity A = Quantity B or No relation. Quantity A: C and D fill a tank in 45 minutes and 30 minutes. Total capacity of the tank(L.C.M of 45 & 30) = 90 units Tank filled by the pipe C in 1 minute = 90/45 ⇒ 2 units Tank filled by the pipe D in 1 minute = 90/30 ⇒ 3 units Tank filled by C and D in 1 minute = 5 units 5 units are filled in 1 minute. ∴ 90 units are filled in 18 minutes i.e (90/5) Time taken by pipes to fill a tank is 18 minutes. Quantity B: 18 minutes ∴ Quantity A = Quantity B |
