The price of the book is marked 20% above the C.P. If the marked price of the book is Rs 180 , then what is the cost of the paper used in a single copy of the book. Paper cost is 25% of d expenditure incurred in publishing a book.
book c.p 150 and 25 % of it is 37.5
Given marked price 180 rs, then find cost price (1.2×cost price=180) why because 20% more than cost price.after this u will get cost price , paper cost is 25% of cost price (0.25×150=37.5)
Absolutely ryt bro ..can u explain d concept pls
