Question
An 84-litre mixture contains 75% milk. If 'x' litres of
water are added to this mixture, the quantity of milk in the resulting mixture becomes 27 litres more than the quantity of water. Determine the value of 'x'.Solution
Quantity of milk in the mixture = 75% of 84 = 63 litres Quantity of water in the mixture = 25% of 84 = 21 litres According to question, 63 – (x + 21) = 27 42 – x = 27 x = 15 litres So, the value of ‘x’ is 15 litres.
