Question
Two mixtures, X and Y, have milk-to-fruit juice ratios of
4:5 and 7:8, respectively. When these two mixtures are combined, the total quantity of the final mixture becomes 1.5 liters, with the milk-to-fruit juice ratio in the final mixture being 37:23. What was the original quantity of mixture X before mixing?Solution
ATQ;
Let quantity of milk and fruit juice in mixture X and Y be 4x ml and 5x ml and 7y ml and 8y ml, respectively.
Quantity of milk in 1500 ml of mixture = 37/60 × 1500 = 925 ml
Quantity of fruit juice in 1500 ml of mixture = 1500 – 925 = 575 ml
So, 4x + 7y = 925
And, 5x + 8y = 575
Solving the above equations, we get;
x = 50 and y = 60
So, quantity of mixture X = 50 × 9 = 450 ml
