q: Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. The capacity of the tank is?
Options:
(A) 299
(B) 2767
(C) 120
(D) 287
(E) 261
a: Stream of consciousness: Work done by the waste pipe in 1 minute = 1/15 - (1/20 + 1/24) = - 1/40
Volume of 1/40 part = 3 gallonsVolume of whole = 3 * 40 = 120 gallons. The answer is (C).

question: What distance will be covered by a bus moving at 72 kmph in 30 seconds?
Options:
(A) 278
(B) 600
(C) 772
(D) 551
(E) 131
answer: Stream of consciousness: 72 kmph = 72 * 5/18 = 20 mps
D = Speed * time = 20 * 30 = 600 m. The answer is (B).
