Question
A mixture contains 40 ml water and rest ‘x’ ml milk.
When 0.5x 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 0.5x ml water = (40 + 0.5x)
Total quantity of the mixture = 40 + 0.5x + x = (40 + 1.5x)
Therefore,
(2/5)(40 + 1.5x) = (40 + 0.5x)
Or, 80 + 3x = 200 + 2.5x
Or, 0.5x = 120
Or, x = 240
