Question

The printed price of a book is $Rs.150$and the discount is $15\% $ Find the actual amount to be paid.

Answer 1

Hint: Here we will solve this question by finding the discount amount given on the book.

Complete step by step solution:
The printed price of a book is $Rs.150$ and the discount given on the printed price is $15\% $.

The printed price of a book = $Rs.150$ (given in the problem statement)
Discount given = $15\% $ (given in the problem statement)
Discount is given on the printed price of the book so as to sell the book at a lower price than the printed price.
Here, the book is being sold at a discount of $15\% $ on the printed book price, that is, the book is to be sold at a $15\% $ lower price than the printed price of a book.

Actual amount to be paid = Printed book price – discount amount
Discount amount = $15\% $ of printed price of a book = $15\% $ of $Rs.150$.
Discount amount = $\frac{{15}}{{100}} \times 150 = 22.5$

Therefore, discount amount on this book is $Rs.22.5$, that is, book is to be sold at $Rs.22.5$ less than the printed book price

Actual amount to be paid = Printed book price – discount amount = $Rs.150 - Rs.22.5 = Rs.127.5$

Hence, the actual amount to be paid is $Rs.127.5$

Note: In this kind of problem, firstly find out the amount of discount and then subtract it from the original price to get the price of the item after the discount.
