Sonu bought 35 books for Rs 676 and sold them at a profit equal to the selling price of 9 books. The selling price of one book is:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Rs 26
Cost price = selling price − profit. With the profit equal to the selling price of 9 books, the cost of 35 books equals the selling price of \(35-9=26\) books.
Let the selling price of one book be Rs \(s\)
Selling price of 35 books \(=35s\), profit \(=9s\)
Cost price \(=35s-9s=26s\)
\(26s=676\)
\(\displaystyle s=\frac{676}{26}=26\)
The selling price of one book is Rs 26.
