Question
A solution contains milk and water in the ratio 4:1. If 25
litres of the 75-litre solution is removed and then 10 litres of water is added, what is the quantity of water in the final mixture?Solution
ATQ,
Total quantity of mixture after removing 25 litres = 75 - 25 = 50 litres
So, quantity of water in the 50 litres mixture = 50 × (1/5) = 10 litres
So, quantity of water in the final mixture = 10 + 10 = 20 litres
