find out the ratio of milk to that of water , if a mixture is formed after mixing milk and water of 3 different vessels containning the mixture of milk to that of water in the proportion 3 : 2 , 7 : 3 , 9 : 2 respectively .
3 + 2 = 57 + 3 = 109 + 2 = 11 now , 3 / 5 + 7 / 10 + 9 / 11 : 2 / 5 + 3 / 10 + 2 / 11 = > 233 / 110 : 97 / 110 = > 233 : 97 answer : a
divide(add(divide(9, add(9, 2)), add(divide(3, add(3, 2)), divide(7, add(7, 3)))), add(divide(2, add(9, 2)), add(divide(2, add(3, 2)), divide(3, add(7, 3)))))
