A bookseller bought 100 copies of a book and marked its price at 40% above the cost price. He sold 40 books giving a discount of 10% and the remaining at a discount of 20%. What is his overall profit percentage?

Sure, let's break it down step by step:

Step 1: Let's assume the cost price of each book is $1. So, the total cost price for 100 books is$100.

Step 2: The bookseller marked the price 40% above the cost price. So, the marked price of each book is $1 + 40$1 = $1.4.

Step 3: He sold 40 books at a discount of 10%. So, the selling price of each of these 40 books is $1.4 - 10$1.4 = $1.26. Therefore, the total selling price for these 40 books is 40 *$1.26 = $50.4.

Step 4: He sold the remaining 60 books at a discount of 20%. So, the selling price of each of these 60 books is $1.4 - 20$1.4 = $1.12. Therefore, the total selling price for these 60 books is 60 *$1.12 = $67.2.

Step 5: The total selling price for all 100 books is $50.4 +$67.2 = $117.6.

Step 6: The total profit is the total selling price minus the total cost price, which is $117.6 -$100 = $17.6.

Step 7: The profit percentage is the total profit divided by the total cost price, times 100%, which is ($17.6 /$100) * 100% = 17.6%.

So, the bookseller's overall profit percentage is 17.6%.

Step 1: Let's assume the cost price of each book is $1. Therefore, the total cost price for 100 books is$100.

Step 2: The bookseller marked the price 40% above the cost price. So, the marked price of each book is $1 + 40$1 = $1.40.

Step 3: He sold 40 books at a discount of 10%. So, the selling price of each of these 40 books is $1.40 - 10$1.40 = $1.26. Therefore, the total selling price for these 40 books is 40 *$1.26 = $50.4.

Step 4: He sold the remaining 60 books at a discount of 20%. So, the selling price of each of these 60 books is $1.40 - 20$1.40 = $1.12. Therefore, the total selling price for these 60 books is 60 *$1.12 = $67.2.

Step 5: The total selling price for all 100 books is $50.4 +$67.2 = $117.6.

Step 6: The overall profit is the total selling price minus the total cost price, which is $117.6 -$100 = $17.6.

Step 7: The overall profit percentage is (profit / total cost price) * 100%, which is ($17.6 /$100) * 100% = 17.6%.

So, the bookseller's overall profit percentage is 17.6%.

Step 1: Let's assume the cost price of each book is $1. Therefore, the cost price for 100 books is$100.

Step 2: The bookseller marked the price 40% above the cost price. So, the marked price of each book is $1 + 40$1 = $1.4. Therefore, the marked price for 100 books is$140.

Step 3: He sold 40 books at a discount of 10%. So, the selling price of each of these 40 books is $1.4 - 10$1.4 = $1.26. Therefore, the total selling price for these 40 books is 40 *$1.26 = $50.4.

Step 4: He sold the remaining 60 books at a discount of 20%. So, the selling price of each of these 60 books is $1.4 - 20$1.4 = $1.12. Therefore, the total selling price for these 60 books is 60 *$1.12 = $67.2.

Step 5: The total selling price for all 100 books is $50.4 +$67.2 = $117.6.

Step 6: The overall profit is the total selling price minus the total cost price, which is $117.6 -$100 = $17.6.

Step 7: The overall profit percentage is (profit / total cost price) * 100%, which is ($17.6 /$100) * 100% = 17.6%.

So, the bookseller's overall profit percentage is 17.6%.

Step 1: Let's assume the cost price of one book is $1. Therefore, the cost price for 100 books is$100.

Step 2: The bookseller marked the price 40% above the cost price. So, the marked price of one book is $1 + 40$1 = $1.40. Therefore, the marked price for 100 books is$140.

Step 3: The bookseller sold 40 books at a discount of 10%. So, the selling price of one book is $1.40 - 10$1.40 = $1.26. Therefore, the selling price for 40 books is$1.26 * 40 = $50.4.

Step 4: The bookseller sold the remaining 60 books at a discount of 20%. So, the selling price of one book is $1.40 - 20$1.40 = $1.12. Therefore, the selling price for 60 books is$1.12 * 60 = $67.2.

Step 5: The total selling price for 100 books is $50.4 +$67.2 = $117.6.

Step 6: The overall profit is the total selling price minus the total cost price, which is $117.6 -$100 = $17.6.

Step 7: The overall profit percentage is (profit / total cost price) * 100%, which is ($17.6 /$100) * 100% = 17.6%.

So, the bookseller's overall profit percentage is 17.6%.

Step 4: The bookseller sold the remaining 60 books at a discount of 20%. So, the selling price of one book is $1.40 - 20$1.40 = $1.12. Therefore, the selling price for 60 books is$1.12 * 60 = $67.2.

Step 5: The total selling price for 100 books is $50.4 +$67.2 = $117.6.

Step 6: The profit is the total selling price minus the total cost price, which is $117.6 -$100 = $17.6.

Step 7: The profit percentage is the profit divided by the cost price, times 100%, which is $17.6 /$100 * 100% = 17.6%.

So, the bookseller's overall profit percentage is 17.6%.
