Answer 1

Answer:

30%

Step-by-step explanation:

Given,

Cost price of 8 books = Selling price of 6 books.

To Find,

Gain percent.

Solution,

Let cost price of one book be x

Cost price of 8 books will be 8x

Selling price of 6 books will be 8x

Selling price of one book is 8x/6 = 1.3x

We know Profit % = (selling price - cost price)/cost price ×100

Profit % = (1.3x - x)/x * 100

= 0.3x/x * 100

= 0.30 * 100

= 30%

There was 30% profit on sale of books.

Result:

Gain = 30%.
