Question

A book seller bought 1000 books. He found that 150 books were lost in the transit and sold the rest at Rs 90 each making a profit of 2%. What was the cost price of each book?​

Answer 1

$\huge\green{\star ANSWER \star}$

Cost price=1000×90=90,000 Rs.

Selling price=90,000−9% of 90,000

=90,000-9/100×90,000

=81,900

So, selling price of each book=81,900/1000

=89
