Answer» Correct Answer - Option 3 : 56.25%

Given:

Cost price of 10 books is Rs. 8

Selling price of 8 books is Rs. 10

Formula Used:

Profit percentage = {(SP – CP)/CP} × 100

Calculation:

Let 40 books (LMC of 8 and 10) were bought.

CP of 40 books = Rs. {(8 × 40)/10} = Rs. 32

Their SP = Rs. (10 × 40/8) = Rs. 50

Profit percentage = (50 – 32)/32 × 100 = 56.25%

∴ Profit% is 56.25%
