Pipe and cistern Example 2
In Pipe and cisterns when we calculate the pipe related examples we first check the nature that if the pipe is filled up by water or any liquid we say the pipe is plus position and when the pipe is vacant we say it as negative, So here we also some example is given. Which help you better understanding.
This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam . Under below given some more example for your better practice .
There is two types Pipes, Pipe 1 and Pipe 2 can fill a water reservoir in 3 and 6 hours respectively . Pipe 3 can empty it in 12 hours. If all the three pipes are opened together, then the water reservoir will be filled in:
Shortcut tricks :
Net part filled in 1 hour = ( 1 / 3 + 1 / 6 – 1 / 12 ) = 5 / 12.
The water reservoir will be full in 12 / 5 hrs.
If A pipe can fill a water reservoir in 12 Hr, and pipes B can empty a water reservoir in 20 Hr, when both pipes are opened simultaneously, How much time will be taken to fill the water reservoir ?
Step 1: At we calculate time taken to fill in hour 1 / 12 hr and time taken to empty the a water reservoir in 1 / 20 hr.
Step 2: When both pipes are opened then time taken to fill
1 / 12 – 1 / 20 = 5 – 3 / 60
2 / 60 = 1 / 30
So in 1 hour to take fill tank both are open A and B 1 / 30
time taken when A and B are opened, A + B = 30 / 1 = 30 Hr.
Pipes X fill the water reservoir in 6 hours, Pipes Y fill the water reservoir in 10 hours, Pipes Z fill the water reservoir in 20 hours, If all the Pipes are open, In how many hours will the water reservoir be filled ?
Shortcut tricks :
Part filled by ( X + Y + Z ) in 1 hour = ( 1 / 6 + 1 / 10 + 1 / 20 ) = 19 / 60.
So, that All the three pipes together will fill the water reservoir in 60 / 19 hours.
