Question

b) A book seller purchased 100 story books at Rs 135 each. She donated 10 books to a school library. If she sold remaining books at 2% loss, find the selling price of each book​

Answer 1

Answer:

100 books at 135 each = 13500 total

with 10 given away , then only (100 - 10 ) = 90 left

so effectively each book now costs 13500/90 = 150

2% of 150 = the loss per book = 150 (2/100) = 3.0

Hence selling price = 150 -3 = 147
