Question
The relationship between the quantity of refined oil and
mustard oil in Mixtures 'P,' 'Q,' and 'R' is described as 7:3, 1:1, and 3:2, respectively. If these mixtures, 'P,' 'Q,' and 'R,' are combined in the ratio of 2:2:3, then what is the proportion of refined oil in the final mixture, expressed as a percentage?Solution
ATQ, % of quantity of Refined oil in mixture ‘P’ = (7/10) × 100 = 70% % of quantity of Refined oil in mixture ‘Q’ = (1/2) × 100 = 50% % of quantity of Refined in mixture ‘R’ = (3/5) × 100 = 60% Hence required % will be = [{(70 × 2) + (50 × 2) + (60 × 3)} ÷ (2 + 2 + 3)] = 420 ÷ 7 = 60%
