Question

X: Capacity of tank? If A can fill the tank in 25 hours and B in 20 hours. C drains 25 litres per hour. If A and B are employed in alternate hours starting from A and C is a permanent leak, It takes 35 hours and 24 minutes to fill the tank. A starts in the first hour. ​

Answer 1

Of this A will be employed for 18 hours, and B will be employed for 17.4 hours. But in the given time tank in filled once due of leak. So leak's contribution = (318/200) - 1 = 118/200 of the capacity of tank. Tank capacity = (885 × 100) ÷ 59 = 1500 litres.
