Answer 1

Question : -

The price of 20 books is Rs. 600. Find the total price of one book.

Answer : -

Price of one book = Rs. 30

Step-by-step explanation : -

Given that,

Cost of one book = Rs. 600

Assumption : -

Let the cost of one book be x.

As, cost of 20 books = Rs. 600

Then, the cost of 1 book will be,

=> x = $\frac{Total\:price}{one\:book's\:price}$

=> x = $\frac{600}{20}$

=> x = $\frac{60\cancel{0}}{2\cancel{0}}$

=> x = $\frac{60}{2}$

=> x = 30

As we've taken x as cost of one book.

Therefore, cost of one book = Rs. 30.

Verification : -

Multiply cost with 20 books, so that, we'll get the price of total 20 books.

Therefore, total cost of 20 books will be,

=> total cost = cost of one book $\times$ total books to be bought.

=> total cost = Rs. 30 $\times$ 20

=> total cost = Rs. 600.

Therefore, hence verified.

Therefore, cost of one book is 300.
