Correct Answer: 28%


Solution : According to the question
Initially, in the 40-litre solution, 10% is water
i.e 0.10 × 4 = 4 litres
When 10 litres of water are added, the total amount of water becomes
= 4 + 10 = 14
The total volume of the new solution = 40 + 10 = 50
⇒ Percentage of water = $\frac{\text{ amount of water​}}{\text{Total Volume}}$×100  = $\frac{14}{50}$×100 = 28%
Hence, the correct answer is  28%
