Two equal glasses are respectively 1/3 and ¼ full of milk. They are then filled up with water and the contents mixed in a tumbler. What is the ratio of milk and water in the tumbler?

Given two equal glasses are respectively one third =1/3 and one fourth full of milk=1/4 total milk in both glass=1/3+1/4=7/12 water in 1st glass=1-1/3=2/3 water in 2nd glass=1-1/4=3/4 total water=2/3+3/4=17/12 then ratio of milk and water =(7/12)/(17/12) =>ratio of milk and water =7:17
