A container contains 36 litres of water. From this container, 6 litres of the content were taken out and replaced by oil. This process was repeated two times. How much water is inside the container?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 25 litres.
Given:
The initial quantity of water in a container is 36 liters
From this container, 6 litres of the content were taken out and replaced by oil.
This process was repeated two times
Formula used:
Final quantity = Initial quantity × (1 - x/C)times
Where, C = capacity of a vessel
x = quantity taken out at one time
Calculation:
Final quantity = 36 × (1 - 6/36)2
⇒ 36 × 5/6 × 5/6 = 25 liters
