Question
In a 600 ml solution, the ratio of milk to water is 3:2.
After adding ‘x’ ml each of milk and water, the ratio becomes 7:5. Determine the value of ‘x’.Solution
ATQ,
Milk = (3/5) × 600 = 360 ml
Water = 600 – 360 = 240 ml
ATQ:
(360 + x)/(240 + x) = 7/5
⇒ 5(360 + x) = 7(240 + x)
⇒ 1800 + 5x = 1680 + 7x
⇒ 2x = 120
⇒ x = 60
