Question

.How many litres of water have to be added to 23 litres of Sikanji (Lemon water ) containing 29%

sugar solution so that the resulting mixture will contain more than 11 % but less than 18% sugar

content. Explain how Sikanji is good for health.​

Answer 1

Answer:

Sol: Volume of lemon water = 23 litres Volume of sugar solution = 29% Volume of sugar solution = (23)(0.29) = 6.67 litres Let the quantity of water to be added = x litres Volume of lemon water after adding the water = (23 + x) Case (i) Percentage of sugar solution after adding the water = 11% (6.67) / (23 + x) = 0.11 6.67 = 2.53 + 0.11x 4.14 = 0.11x x = 37.63 Case (ii) Percentage of sugar solution after adding the water = 18% (6.67) / (23 + x) = 0.18 6.67 = 4.14 + 0.18x 2.53 = 0.18x x = 14.05 Therefore, 14.05 litres to 37.63 litres of water should be added to 23 litres of lemon water so that the resulting mixture will contain more than 11% but less than 18% sugar content.
