Question
600 ml of mixture contains milk and water in the ratio
of 3:2. If `x` ml of milk and `(x - 40)` ml of water are added, then the ratio becomes 7:5. Find the value of `x`.Solution
Milk = (3/5) × 600 = 360 ml
Water = (2/5) × 600 = 240 ml
(360 + x)/(240 + x - 40) = 7/5
5(360 + x) = 7(200 + x)
1800 + 5x = 1400 + 7x
2x = 400
⇒ x = 200
