Answer» Correct Answer - Option 3 : 25 % Given: Cost price of 100 notebooks = Selling price of 80 Note Books Formula used: \({\rm{Profit\;\% }} = \frac{{{\rm{Profit}}}}{{{\rm{Cost\;price}}}} × 100\) Profit = Selling price(S.P.) - Cost Price(C.P.) Calculation: Let C.P. of 100 notebooks be 100x S.P. of 80 notebooks be 80x C.P. × 100x = S.P. × 80x ⇒ C.P./S.P. = 80/100 = 4/5 Profit = 5 - 4 = 1 Profit % = (1/4) × 100 = 25% ∴ The percent Gain is 25% |
