Question
180 litres of a mixture contains 36% milk and rest
water. If ‘x’ litres of milk is added into the mixture then quantity of water in the final mixture becomes 60% of total quantity of mixture. Find the value of ‘x’.Solution
Quantity of milk in the initial mixture = 180 × 0.36 = 64.8 litres Quantity of water in the initial mixture = 180 – 64.8 = 115.2 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (76.8/60) × 100 = 192 litres Quantity of milk in final mixture = 192 – 115.2 = 76.8 litres Value of ‘x’ = 76.8 – 64.8 = 12
