Question
130 litres of a mixture contains 35% milk and rest
water. If ‘x’ litres of milk is added into the mixture then quantity of water in the final mixture becomes 50% of total quantity of mixture. Find the value of ‘x’.Solution
Quantity of milk in the initial mixture = 130 × 0.35 = 45.5 litres Quantity of water in the initial mixture = 130 – 45.5 = 84.5 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (84.5/50) × 100 = 169 litres Quantity of milk in final mixture = 169 – 84.5 = 84.5 litres Value of ‘x’ = 84.5 – 45.5 = 39
564.932 + 849.029 – 425.08 = 612.095 + ?
999.99 + 99.99 + 99= ?
