Given : 480 ml of a mixture contains milk and water in the ratio 4:2
To Find : How much more water is to be added to get a new mixture containing milk and water in the ratio 4:3?
Solution:
480 ml of a mixture contains milk and water in the ratio 4:2
Milk = { 4/(4 + 2) } × 480 = 320 ml
Water = { 2/(4 + 2) } × 480 = 160 ml
Water added = x ml
Milk = 320 ml Water = 160 + x ml
New ratio = 4 : 3
=> 320 / ( 160 + x) = 4/3
=> 960 = 4 ( 160 + x)
=> 240 = 160 + x
=> x = 80
80 ml more water is to be added to get a new mixture containing milk and water in the ratio 4:3
