If 60 litres of a milk solution has 40% milk in it, then how much milk should be added to make the milk 60% in the solution?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 30 litres.
Given:
60 litres of a milk solution has 40% milk in it
Explanation:
The quantity of milk in the solution = 60 × 40/100 = 24 litres
The quantity of water in the solution = 60 - 24 = 36 litres
According to the question
If milk should be added to the solution,
So, the quantity of water will be same in the new solution = 36 litres
⇒ 40% = 36
⇒ 60% = 36 × 60/40
⇒ 54 litres
Hence, Milk will be added to the solution = 54 - 24
⇒ 30 litres
