Question
A 360 ml solution consists of milk and water in the
ratio 2:3. If ‘x’ ml of milk and the same amount of water is added, the new ratio of milk to water becomes 5:7. Find the value of ‘x’.Solution
ATQ,
Quantity of milk in 360 ml = (2/5) × 360 = 144 ml
Quantity of water = 360 – 144 = 216 ml
ATQ:
(144 + x)/(216 + x) = 5/7
⇒ 7(144 + x) = 5(216 + x)
⇒ 1008 + 7x = 1080 + 5x
⇒ 2x = 72
⇒ x = 36
