Question
Two mixtures, P and Q, have milk-to-sugar ratios of 8:11
and 10:15, respectively. When these two mixtures are combined, the total quantity of the final mixture becomes 0.9 liters, with the milk-to-sugar ratio in the final mixture being 5:7. What was the original quantity of mixture Q before mixing?Solution
ATQ;
Let quantity of milk and sugar in mixture P and Q be 8x ml and 11x ml and 10y ml and 15y ml, respectively.
Quantity of milk in 900 ml of mixture = 5/12 × 900 = 375 ml
Quantity of sugar in 900 ml of mixture = 900 – 375 = 525 ml
So, 8x + 10y = 375
And, 11x + 15y = 525
Solving the above equations, we get;
x = 15 and y = 20
So, quantity of mixture Q = 20 × 25 = 500 ml
