A leak at the bottom of the tank can empty the tank in 5 hours, while an inlet pipe can fill the same tank at the rate of 6 litres per minute. When the tank is full, the inlet is opened and the tank gets empty in 8 hours due to the leakage. Find the capacity of the tank.

A.	1800 litres	B.	3600 litres
C.	4800 litres	D.	5760 litres

Answer and Explanation

Answer:4800 litres

Explanation:
The capacity of the tank is given by C = (p*q*r)/(r â€“ p) litres
Where, p = time in which the leakage can empty the tank in hours = 5 hours
q = rate at which the inlet fills the tank in lph = 6*60 = 360 lph
r = time in which the tank gets emptied in hours = 8 hours
Hence, C = (5*360*8)/(8 â€“ 5)
C = 4800 litres
