Show answer & explanation
Correct answer: D
Step 1: Find the amount of sugar initially. 25 litres × 20% = 5 litres of sugar.
Step 2: Find the remaining volume after evaporation. 25 litres − 10 litres = 15 litres. The sugar amount remains 5 litres (only solvent evapourates).
Step 3: Compute the new percentage of sugar. (5 ÷ 15) × 100% = 33.333...% ≈ 33.33%.
Answer: 33.33%.
