There is 10% water in a 40-litre solution of milk and water. If 10 litres of water are added to this solution, then what percentage of the new solution will be water?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 28%.

Given :

To tal solution = 40L

Amount of water = 10% of 40 L 

Amount of water added = 10 L

Explanation :

Amount of water in the solution = 10% of 40 L = 4 L

Amount of milk in the solution = 40 - 4 = 36 L

Amount of water after addition = 4 + 10 = 14 L

Now, total solution = 36 + 14 = 50 L

Required percentage = (14/50) × 100 = 28 %

Hence the required percentage is 28%.
