Question
In a mixture of milk & water, 40 litres water is mixed
due to which ratio changes from 3 : 4 to 1 : 4. Find initial quantity of mixture. (in litres)Solution
let initial quantity of milk be 3x litres & water be 4x litres. ATQ, 3x/4x+40 = 1/4 12x = 4x + 40 ⇒ x = 5 Initial quantity of mixture = 3x + 4x = 35 liters
