40 litres of milk are kept in a container. 4 litres of milk were removed from this container and replaced with water. This procedure was performed two more times. How much milk does the container now hold?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 29.16 litres
Given that
Initially, we had 40 liters of milk
4 liter is replaced with water 3 times
Formula used
Final quantity = Initial quantity * [1 - (replace quantity/total quantity)]times
Calculation
Final quantity = 40 * (1-(4/40))3
= 40 * (9/10)3 = 40 * 729/1000 = 29.16 litres
