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

Answer:

SP of each book is  rupees 19

Step-by-step explanation:

In context to the equation  it is asked to find  the SP of each book means 1 book    

The data  is given as follows

Number of copies sold=200

loss of 5% =

book cost =20

we need to find the selling price of 1 book

so first find amount actual sold of 200 books

$=200\times 20\\= 4000$

so 4000 is the selling price of 200 books

It is given he sold at a loss of 5%

so we need to find 5% of 4000

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

$=\frac{5}{100} \times 4000\\=200$

so after loss calculation the amount of loss of 200 books

He sold at =4000

5% loss =200

so

4000 -200

   =3800

so 3800 is the amount of selling 200 copies and it is asked to find the selling price of each means 1 copy

$\frac{3800}{200} \\=19 rupees$
