Tap A, B and C are connected to a water tank and the rate of flow of water is 42 litres/hr, 56 litres/ hr and 48 litres/hr respectively. Tap A andB fill the tank while tap C empties the tank. If all the three taps are opened simultaneously, the tank gets completely filled up in 16 hours. What is the capacity of the tank?
-
- 960 litres
- 2346 litres
- 1600 litres
- 800 litres
- 960 litres
Correct Option: D
From the question ,
When all three taps are opened simultaneously, Net amount of water filled in the tank in 1 hour = 42 + 56 – 48 litres = 50 litres
The tank gets completely filled in 16 hours.
∴ Capacity of the tank = Net amount of water × Time
∴ Capacity of the tank = 16 × 50 = 800 litres
