Question 1 of 5
1. Question
Three pipes R, A and B can fill the tank. R can fill the tank 5 minutes less than that of B. If all the pipes are opened together and pipe B is turned off 5 minutes before the tank is filled. Then find the time in which the tank will full.
Correct
Let total time taken by the pipes is X hrs,
(1/5 + 1/10 + 1/15) *(X â€“ 5) + (1/5 + 1/15) *5 = 45/11Incorrect
Let total time taken by the pipes is X hrs,
(1/5 + 1/10 + 1/15) *(X â€“ 5) + (1/5 + 1/15) *5 = 45/11 
Question 2 of 5
2. Question
Two pipes I and J are opened simultaneously and it is found that due to leakage in the bottom of the tank it took 48 minutesâ€™ excess time to fill the cistern. When is the cistern full, in what time will the leak empty it?
Correct
Work done by the two pipes in 1 hour = (1/12) + (1/18)
= (15/108).
Time taken by these pipes to fill the tank = (108/15) hrs
= 7 hours 12 min.
Due to leakage, time taken = 7 hours 12 min + 48 min
= 8 hours
Work done by two pipes and leak in 1 hour = 1/8.
Work done by the leak in 1 hour = (15/108) (1/8) =
(1/72).
Leak will empty the full cistern in 72 hours.Incorrect
Work done by the two pipes in 1 hour = (1/12) + (1/18)
= (15/108).
Time taken by these pipes to fill the tank = (108/15) hrs
= 7 hours 12 min.
Due to leakage, time taken = 7 hours 12 min + 48 min
= 8 hours
Work done by two pipes and leak in 1 hour = 1/8.
Work done by the leak in 1 hour = (15/108) (1/8) =
(1/72).
Leak will empty the full cistern in 72 hours. 
Question 3 of 5
3. Question
A waste pipe, W can carry off 12 litre of water per minute. If all the pipes M, N and W, are opened when the tank is full and it takes one hour to empty the tank. Find the capacity of the tank.
Correct
Let the waste pipe take â€˜Xâ€™ time to empty the tank.
(1/10 + 1/12 â€“ 1/X) *60 = 1
we will get X = 5 min
so capacity = 5*12 = 60ltrIncorrect
Let the waste pipe take â€˜Xâ€™ time to empty the tank.
(1/10 + 1/12 â€“ 1/X) *60 = 1
we will get X = 5 min
so capacity = 5*12 = 60ltr 
Question 4 of 5
4. Question
Two pipes K, and L are opened and when the tank is 1/3 full a leak is developed due to which 1/3 water supplied by the pipe leaks out. What is the total time to fill the tank?
Correct
(1/15 + 1/30) *T1 = 1/3, T1 = 10/3 minutes
Now after leak is developed,
[(1/15 + 1/30) â€“ (1/3) *(1/15 + 1/30)] *T2 = 2/3
T2 = 10 minutes.
So total time = 10 + 10/3 = 40/3 minutesIncorrect
(1/15 + 1/30) *T1 = 1/3, T1 = 10/3 minutes
Now after leak is developed,
[(1/15 + 1/30) â€“ (1/3) *(1/15 + 1/30)] *T2 = 2/3
T2 = 10 minutes.
So total time = 10 + 10/3 = 40/3 minutes 
Question 5 of 5
5. Question
Three pipes N, C and D can fill a tank. If pipe N is opened all the time and pipe C and D are
opened for one hour alternatively. The tank will be full inCorrect
(1/12 + 1/15) + (1/12 + 1/20) = 17/60 (in 2 hrs this
much tank is filled)
so in 6 hrs 51/60 is filled.
Remaining, 9/60 = (1/12 + 1/15) *T, so T = 1hr
so total = 6 + 1 = 7 hrIncorrect
(1/12 + 1/15) + (1/12 + 1/20) = 17/60 (in 2 hrs this
much tank is filled)
so in 6 hrs 51/60 is filled.
Remaining, 9/60 = (1/12 + 1/15) *T, so T = 1hr
so total = 6 + 1 = 7 hr
