Question
A mixture of 140 lit contains milk and water where milk
is 20 lit more than water. If 28 lit mixture is taken out and 12 lit pure milk is added then ratio of milk and water becomes 39:R. Find value of R.Solution
Ratio of milk and water in the mixture = 80:60 = 4/3 Now, 28 liter of mixture is taken out and 12 liter pure milk is added so, ratio of milk and water becomes => (80 – 28×4/7) + 12/(60 – 28×3/7) = 39/R => 78/48 = 39/R => R = 24
