Question

Amina buys a book for INR 275, and sells it at a loss of 15%. How much does she sell it for.

Answer 1

Hint: In this question, the concept of percentages, cost and selling price will be used. We have to read the language of the question and form the equation accordingly, to find the correct answer. To convert percentage into decimal, we divide it by hundred.

Complete step by step answer:
The cost price of the book is Rs 275. Let the selling price be Rs x. It is given that she sells it at a loss of 15%. That means the selling price is 15% less than the cost price.
So,
275 - (15% of 275) = x
Dividing the percentage by 100,
275 - 0.15 x 275 = x
x = 275 - 41.25
x = Rs 233.75
Hence, Amina sells the book for Rs 233.75. This is the required answer.
Note: In such types of questions, understanding the language of the question is the key. Look for words like ‘buy’, ‘sell’, ‘profit’, ‘loss’ and so on. We need to form the equation according to the language. Also, write the correct units or currency with the final answer.
