Passage

Study the paragraph carefully and answer the following questions. Cetking sold three books i.e. Quant, English and reasoning on three different stores i.e. A, B and C. Quant, reasoning and English book are sold at 20% discount by store A, C and B respectively. Quant, reasoning and English book are sold at 15% discount by store C, B and A respectively. Discount percent given on Quant book by store B is half of discount percent given on reasoning book by store C. M.R.P. for each book is same at every store.

If market price of a reasoning book was 50% more than cost price of the book for store C. Find profit percent on selling a reasoning book by store C?

The discount percentage on the reasoning book by store C is 15%, which is half of the 30% discount given on the reasoning book by store B. Let the marked price of the reasoning book be Rs. 100, meaning it is sold at store C for Rs. 85. The marked price is 50% more than the cost price for store C, so the cost price is 100 divided by 1.5, which is approximately Rs. 66.67. The profit is calculated by finding the difference between the selling price and the cost price, dividing it by the cost price, and multiplying by 100, resulting in ((85 - 66.67) divided by 66.67) multiplied by 100. This calculation results in a profit percent of 20.
