Answer» Correct Answer - Option 3 : 35 : 61 Given: The quantity of mixture is 576 ml. The ratio of milk to water is 7 : 5. 37.5% of the mixture is taken out. Calculation: The ratio of milk to water is 7 : 5. The quantity of mixture is 576 ml. Then, the quantity of milk = 7/12 × 576 = 336 ml The quantity of water = 5/12 × 576 = 240 ml According to the question, 37.5% of the mixture is taken out. The mixture taken out = 37.5/100 × 576 = 216 ml Then, the milk taken out = 37.5/100 × 336 = 126ml The water taken out = 37.5/100 × 240 = 90 ml Remaining milk = 336 - 126 = 210 ml Remaining water = 240 - 90 = 150 ml The216 ml of water added in the remaining mixture. Then, the resultant water = 216 + 150 = 366 ml The ratio of resultant milk to water = 210 : 366 = 35 : 61 Therefore, the ratio of milk to water in the resultant mixture is 35 : 61. |
