Question
A 840 ml mixture contains milk and water in the ratio 7:5.
If ‘x’ ml each of milk and water is poured into it, the new ratio of milk to water becomes 6:5. What is x?Solution
ATQ,
Milk = (7/12) × 840 = 490 ml
Water = 840 – 490 = 350 ml
ATQ:
(490 + x)/(350 + x) = 6/5
⇒ 5(490 + x) = 6(350 + x)
⇒ 2450 + 5x = 2100 + 6x
⇒ x = 350
