সমাধান
সঠিক উত্তর: Option B
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
