Question
In a vessel, milk and water are present in the ratio 7:4.
If 18 ml of the solution is removed and replaced with 12 ml of milk, the new milk to water ratio becomes 5:2. Find the original volume of the solution.Solution
ATQ,
Let milk and water after removal = 7x ml and 4x ml.
Milk after adding 12 ml = (7x + 12) ml
ATQ,
{(7x + 12) / 4x} = 5/2
So, 14x + 24 = 20x
So, 20x - 14x = 24
So, 6x = 24
So, x = 4
So, total quantity = 7×4 + 4×4 + 18 = 28 + 16 + 18 = 62 ml
