Question

A BOOK SELLER SOLD 200 COPIES OF A BOOK AT A LOSS 5%. IF A BOOK COSTS HIM RUPEES 20, FIND THE SELLING PRICE OF EACH BOOK.

Answer 1

Given,

The number of copies of the book is 200.

The loss percentage is 5.

The cost price of each book is rupees 20.

To find,

The selling price of each book.

Solution,

The cost price of each copy is rupees 20.

The cost price of 200 copies is rupees (20 X 200) = rupees 4000.

Now, the books are sold at a loss of 5 percent.

Therefore, the loss amount is $\frac{5}{100}(4000)=200$

The selling price for 200 books is (4000 - 200), that is, rupees 3800.

The selling price of each copy  is (3800/200) = rupees 19.

Hence, the selling price of each book will be rupees 19.
