Question
The ratio of cost prices of two articles ‘A’ and
‘B’ is 5:4 respectively and the average cost price of articles ‘A’ and ‘B’ is Rs. 1800. If articles ‘A’ and ‘B’ are sold at profit of 22% and profit of Rs. 210 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. 5y and Rs. 4y respectively Sum of cost price of articles ‘A’ and ‘B’ = 1800 × 2 = 3600 => 5y + 4y = 3600 => 9y = 3600 => y = 400 So, cost price of article ‘A’ = 5y = Rs. 2000 Cost price of article ‘B’ = 4y = Rs. 1600 Selling price of article ‘A’ = 2000 × (122/100) = Rs. 2440 Selling price of article ‘B’ = 1600 + 210 = Rs. 1810 So, average selling price of given two articles = (2440 + 1810) ÷ 2 = Rs. 2125
