25%

20%

35%

28%

Alright, let’s break this down step by step:

- You start with a 40-litre mixture. Only 10% is water, so that’s 4 litres of water, and the rest—36 litres—is milk.

- You add 10 litres of water. Now, water in the solution is 4 + 10 = 14 litres.

- The new total volume? 40 + 10 = 50 litres.

Now, the calculation:

- Percentage of water = (14/50) × 100 = 28%

Looking at the options:

- Option 1 (25%): That would need 12.5 litres water in 50 litres—doesn’t fit.

- Option 2 (20%): Only 10 litres water in 50 litres—not right.

- Option 3 (35%): That’s 17.5 litres in 50—way too much.

- Option 4 (28%): That matches perfectly.

Option 4: 28% is spot on.
