Question
The ratio of cost prices of two articles ‘A’ and
‘B’ is 1:3 respectively and the average cost price of articles ‘A’ and ‘B’ is Rs. 1200. If articles ‘A’ and ‘B’ are sold at profit of 22% and profit of Rs. 200 respectively, then what is the average selling price of the given two articles?Solution
Let the cost price of articles ‘A’ and ‘B’ be Rs. y and Rs. 3y respectively Sum of cost price of articles ‘A’ and ‘B’ = 1200 × 2 = 2400 => y + 3y = 2400 => 4y = 2400 => y = 600 So, cost price of article ‘A’ = y = Rs. 600 Cost price of article ‘B’ = 3y = Rs. 1800 Selling price of article ‘A’ = 600 × (122/100) = Rs. 732 Selling price of article ‘B’ = 1800 + 200 = Rs. 2000 So, average selling price of given two articles = (732 + 2000) ÷ 2 = Rs. 1366
