Verified Answer
Two pipes A and B can fill a tank in 12 hours and 18 hours respectivel...
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.
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.

Two pipes A and B can fill a tank in 12 hours and 18 hours respectivel...
Given information:
- Pipe A can fill the tank in 12 hours.
- Pipe B can fill the tank in 18 hours.
- Due to a leakage, it took an additional 48 minutes to fill the tank.
Let's calculate the filling rates of pipes A and B:
- Pipe A fills 1/12th of the tank in 1 hour.
- Pipe B fills 1/18th of the tank in 1 hour.
Let's assume the capacity of the tank is T and the rate of leakage is L (in liters per hour).
Filling the tank without leakage:
- Pipe A fills the tank in T/12 hours.
- Pipe B fills the tank in T/18 hours.
Filling the tank with leakage:
- Pipe A fills the tank in (T/12 + 48/60) hours (converted 48 minutes to hours).
- Pipe B fills the tank in (T/18 + 48/60) hours.
Since both pipes are opened simultaneously, their combined filling rate is the sum of their individual rates:
- Pipe A and B together fill 1/12 + 1/18 = 5/36th of the tank in 1 hour.
Finding the time taken to fill the tank with leakage:
- Pipe A and B together fill the tank in (T/12 + 48/60) hours.
- In 1 hour, they fill 5/36th of the tank.
- So, (T/12 + 48/60) * (5/36) = T
Simplifying the equation:
- (T/12 + 48/60) * (5/36) = T
- (5T + 4T) / (12*5) = T
- (9T/60) = T
- 9T = 60T
- 9T - 60T = 0
- -51T = 0
- T = 0
Since the time taken to fill the tank with leakage is 0, it means the leak is emptying the tank faster than the combined filling rate of pipes A and B.
Therefore, the leak will empty the tank in a certain amount of time. The correct answer option is A) 72 hours.
- Pipe A can fill the tank in 12 hours.
- Pipe B can fill the tank in 18 hours.
- Due to a leakage, it took an additional 48 minutes to fill the tank.
Let's calculate the filling rates of pipes A and B:
- Pipe A fills 1/12th of the tank in 1 hour.
- Pipe B fills 1/18th of the tank in 1 hour.
Let's assume the capacity of the tank is T and the rate of leakage is L (in liters per hour).
Filling the tank without leakage:
- Pipe A fills the tank in T/12 hours.
- Pipe B fills the tank in T/18 hours.
Filling the tank with leakage:
- Pipe A fills the tank in (T/12 + 48/60) hours (converted 48 minutes to hours).
- Pipe B fills the tank in (T/18 + 48/60) hours.
Since both pipes are opened simultaneously, their combined filling rate is the sum of their individual rates:
- Pipe A and B together fill 1/12 + 1/18 = 5/36th of the tank in 1 hour.
Finding the time taken to fill the tank with leakage:
- Pipe A and B together fill the tank in (T/12 + 48/60) hours.
- In 1 hour, they fill 5/36th of the tank.
- So, (T/12 + 48/60) * (5/36) = T
Simplifying the equation:
- (T/12 + 48/60) * (5/36) = T
- (5T + 4T) / (12*5) = T
- (9T/60) = T
- 9T = 60T
- 9T - 60T = 0
- -51T = 0
- T = 0
Since the time taken to fill the tank with leakage is 0, it means the leak is emptying the tank faster than the combined filling rate of pipes A and B.
Therefore, the leak will empty the tank in a certain amount of time. The correct answer option is A) 72 hours.
