Answer» Correct Answer - Option 4 : 21% Formula used: Profit = SP – CP Profit % = Profit/CP × 100 Here, CP and SP are cost price and selling price respectively Calculation: CP of 11 m cloth = 100 CP of 1 m cloth = 100/11 And, SP of 10 m cloth = 110 SP of 1 m cloth = 110/10 = 11 Profit = SP of 1 m cloth – CP of 1 m cloth ⇒ 11 – 100/11 ⇒ (121 – 100)/11 ⇒ 21/11 Profit % = [(21/11)/(100/11)] × 100 ⇒ 21% ∴ The profit percentage is 21% |
