Detailed Solution
Download Solution PDFGiven:
Initial solution = 3 litres
Sugar concentration in initial solution = 40%
Sugar in initial solution = 40% of 3 litres
Water added = 1 litre
Total solution after adding water = 3 + 1 = 4 litres
Formula used:
Sugar concentration = (Sugar quantity / Total solution) × 100
Calculation:
Sugar in initial solution = 40% of 3 = (40 / 100) × 3 = 1.2 litres
Total solution = 4 litres
New sugar concentration = (Sugar quantity / Total solution) × 100
⇒ (1.2 / 4) × 100
⇒ 0.3 × 100 = 30%
∴ The correct answer is option (3).
