Answer» From statement I, we can just get the rate of flow of outlet tap. From statement II alone it is not possible to get the answer. Now combining Statement I and II, Tap 1 takes 20 minutes and tap 2 takes 30 minutes ⇒ The time taken by both to fill the tank is given as follows, Let the total capacity of the tank be ( = LCM of 20 and 30) 60 units. ⇒ Tank filled by tap 1 in 1 minute = 60/20 = 3 units ⇒ Tank filled by tap 2 in 1 minute = 60/30 = 2 units ⇒ Tank filled by both the taps in 1 minute = 5 units ⇒ Tap 1 and 2 will require 60/5 = 12 minutes to fill the tank together and half of the tank in 6 minutes. From statement II, the outlet tap takes 24 minutes to fill the empty tank. ⇒ It takes (24 – 6) = 18 minutes to fill the tank when outlet tap is open. ∴ Hence the capacity of the tank is 18 × 100 = 1800 liters. ∴ Data given in both the statement I and II are necessary to answer the question. |
