Question
A solution of 960 ml has milk and water in 1:3 ratio. If an
equal quantity of milk and water is added and the new ratio becomes 2:5, calculate the value of x.Solution
ATQ,
Milk = (1/4) × 960 = 240 ml
Water = 960 – 240 = 720 ml
ATQ:
(240 + x)/(720 + x) = 2/5
⇒ 5(240 + x) = 2(720 + x)
⇒ 1200 + 5x = 1440 + 2x
⇒ 3x = 240
⇒ x = 80
