Question
In a mixture of milk and water,
the amount of milk is (p + 40) and the amount of water is 40 litres. After adding 20Â litres of milk and 8Â litres of water to this mixture, the ratio of milk to water becomes 5:3. What is the value of p%, representing the % of water in the original mixture?Solution
ATQ, So, we can say, [p + 40 + 20]/(40 + 8) = 5/3 Or, 3p + 180 = 48 × 5 = 240 Or, 3p = 60, or, p = 60/3 = 20 Required value is = 40 × (20/100) = 8 litres
