Question
A mixture contains 30 ml water and rest ‘x’ ml milk.
When 0.6x ml of water is added to the mixture, the quantity of water becomes 2/5th of the mixture. Find the value of ‘x’.Solution
According to the question,
Quantity of water after addition of 0.6x ml water = (30 + 0.6x)
Total quantity of the mixture = 30 + 0.6x + x = (30 + 1.6x)
Therefore,
(2/5)(30 + 1.6x) = (30 + 0.6x)
Or, 60 + 3.2x = 150 + 3x
Or, 0.2x = 90
Or, x = 450
