Given  : एक टाकी एका नळाने 20 तासात भरते मात्र टकीस ्छिद्र असल्याने टाकी 5 तास उशीरा भरते  

A tank is filled in 20 hrs but due to a hole it taken 5 hrs more

To Find : पूर्णपणे भरलेली टाकी  छिद्राने किती तासात खाली होईल

In how much time tank will drain filled tank

Solution:

Let say Fulled tank   = 100P

A tank is filled in 20 hrs by a Tap

Tap fill in 1 hr  = 100P/20  = 5P

 tank is filled in 20 + 5  = 25 hrs by a Tap  with hole

Tap +  hole fill in 1 hr  = 100P/25  = 4P  

5P +  hole fill in 1 hr = 4P

=>  hole fill in 1 hr  = -P

-ve sign shows drain

=> hole drain  in 1 hr  = P

Complete tank wil be drained  = 100P/P  = 100 hrs
