Answer 2

Given: The cash discount is 10% on a book.

To find: If cash discount is 10% a book bought for Rs. 9 is valued at

Solution:

Let the original value of the book be x. The 10% discount on the book can be calculated as shown below.

$discount = \frac{10}{100}* x$

              $= \frac{x}{10}$

Now, the discounted value of the book can be calculated as follows.

$x - \frac{x}{10}$

According to the question, the book is valued at Rs. 9 after the discount. Hence, the discounted value can be equated to 9.

$x - \frac{x}{10} = 9$

$\frac{9x}{10} = 9$

$x= 10$

Therefore, if cash discount is 10% a book bought for Rs. 9 is valued at Rs. 10.
