Question
Mixture X has acid and petrol in the ratio 11:9. Mixture
Y has 25% acid, the rest water. If 36 litres of mixture X is blended with 24 litres of mixture Y, what is the % of acid in the final mixture?Solution
ATQ,
% of acid in mixture X = 100 Γ (11/20) = 55% So, total quantity of acid in the newly formed mixture = 36 Γ 0.55 + 24 Γ 0.25 = 19.8 + 6 = 25.8 litres Total quantity of the newly formed mixture = 36 + 24 = 60 litres So, required % = (25.8/60) Γ 100 = 43%
