Due to leakage in a tank, it empties in 6 hours. An inlet pipe fills the water at 4 litres per minute. If the tank is full and inlet is opened the tank empties in 8 hours because of the leakage. What is the capacity of the tank in litres?
Answer: C
Work done by the inlet in 1 hour =
1/6−1/8=1/24
Work done by inlet in 1 min=1/24∗1/60=1/1440
=>Volume of 1/1440 part
= 4 liters
Volume of whole = (1440 * 4) litres = 5760 litres.
