Jamil can fill a pool carrying bucket of water in 30 minutes ali can do the same job in 45 minutes tariq can do the same job in 60 minutes how quickly can all three fill the pool together?
Jamil fills 1/30 of the pool in one minute.
Ali fills 1/45 of the pool in one minute.
Tariq fills 1/60 of the pool in one minute.
So, together they fill 1/30 + 1/45 +1/60 = 6/180 + 4/180 +3/180
= 13/180 of the pool in one minute.
Therefore, it takes them 180/13 minutes to fill th pool
together.
That is, 13.85 minutes.
