Question
In a mixture of milk & water, 80 litres water is mixed
due to which ratio changes from 3 : 4 to 1 : 3. Find initial quantity of mixture. (in litres)Solution
let initial quantity of milk be 3x litres & water be 4x litres. ATQ, 3x/4x+ 80 = 1/3 9x = 4x + 80 ⇒ x = 16 Initial quantity of mixture = 3x + 4x = 112 liters
