Question
A solution ‘ABC’ has 15% sugar. Another solution
‘XYZ’ has 5% sugar. How many liters of the solution ‘XYZ’ must be added to the 25 litre of solution ‘ABC’ to make a solution of 10% sugar?Solution
Let required amount of solution ‘XYZ’ to be added = x litre Then, => (15 × 25 + 5x)/(25 + x) = 10 => 375 + 5x = 250 + 10x => 5x = 125 => x = 25
