Pipe and Cisterns (MCQ )

1. Two taps A and B can fill a tank in 5 hours and 20 hours respectively. If both the taps are open then due to a leakage, it took 30 minutes more to fill the tank. If the tank is full, how long will it take for the leakage alone to empty the tank?
(a) 44 hrs
(b) 12 hrs
(c) 18 hrs
(d) 36 hrs

2. Two pipes A and B together can fill a cistern in 4 hours. Had they been opened separately, then B would have taken 6 hours more than A to fill the cistern. How much time will be taken by A to fill the cistern separately?
(a) 10 hr
(b) 4 hrs
(c) 6 hrs
(d) 8 hrs.

3. One pipe can fill a tank three times as fast as another pipe. If together the two pipes can fill the tank in 36 minutes, then the slower pipe alone will be able to fill the tank in:
(a) 92 min
(b) 112 min
(c) 144 min
(d) 192 min

4. A tank is filled in 5 hours by three pipes A, B and C. The pipe C is twice as fast as B and B is twice as fast as A. How much time will pipe A alone take to fill the tank?
(a) 22 hrs
(b) 27 hrs
(c) 35 hrs
(d) cannot be determined

5. A tank is filled by three pipes with uniform flow. The first two pipes operating simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hours faster than the first pipe and 4 hours slower than the third pipe. The time required by the first pipe is:
(a) 8 hrs
(b) 13 hrs
