Question
A solution has milk and water in the proportion 3:2. After
removing 20 ml of this solution and adding 10 ml milk, the ratio becomes 4:1. Find the total volume of the original solution.Solution
ATQ,
Let milk and water after removal be 3x ml and 2x ml.
Milk after adding 10 ml = (3x + 10) ml
ATQ,
{(3x + 10) / 2x} = 4/1
So, 3x + 10 = 8x
So, 8x - 3x = 10
So, x = 2
So, total quantity = 3×2 + 2×2 + 20 = 6 + 4 + 20 = 30 ml
