Question
145 litres of a mixture contains 40% milk and rest
water. If ‘x’ litres of milk is added into the mixture then quantity of water in the final mixture becomes 25% of total quantity of mixture. Find the value of ‘x’.Solution
Quantity of milk in the initial mixture = 145 × 0.40 = 58 litres Quantity of water in the initial mixture = 145 – 58 = 87 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (87/25) × 100 = 348 litres Quantity of milk in final mixture = 348 – 87 = 261 litres Value of ‘x’ = 261 – 58 = 203
