Question
Marked price, selling price and cost price of an
article are in the ratio 13:10:8. If difference between marked price and cost price of an article is Rs. 1250 then find out the profit on the article. TYPE 30Solution
Let the MP, SP and CP on an article be 13x, 10x and 8x respectively. According to question, => (13x – 8x) = 1250 => 5x = 1250 => x = 250 Now, Profit = SP – CP => Profit = (10x – 8x) = 2x = Rs.500
