Ratio of MP and SP of an article is 9:6 and the article
is sold at 20% profit. Find cost price of article, if the selling price is 100 more than its CP?Solution
Let the MP and SP be 900x and 600x respectively. => 120% of CP = 600x => CP = 500x According to questions, => SP = CP + 100 => 600x = 500x + 100 => 100x = 100 => x = 1 Cost price = 500x = Rs.500
