Question

cost price of each book is 175 Rs. If the publisher wants to gain 4%, what price should be printed on the book?​

Answer 1

Step-by-step explanation:

Cost price of books = 1200 * 60 = Rs. 72000

No.of books given free = 300

Hence, no.of books sold = 900

Since 2 books are given free for every 18 books, then no.of books given free for 900 books = 900/20 * 2 = 90

Hence no.of books sold at a price = 810

Let x be the selling price of each book.

Then we have, 810 * x = 72000 * 117/100

x = 8 * 117/9 = Rs. 104
