A vessel contains 80 litres of milk. 16 litres of milk was taken out of the vessel and replaced by water. Then 16 litres of mixture was withdrawn and again replaced by water. The operation was repeated for third time. How much milk is now left in the vessel?
-
- 96.40 litres
- 50.36 litres
- 40.96 litres
- 32.76 litres
Correct Option: C
Amount of milk left = 80 [1 - (16 / 80)]3 = 80 (4 / 5)3
80 × (64 / 125) = 40.96 liters.
