Because after getting selling price we can get profit or loss, then we can calculate profit% or loss% So lets solve this: Price Received by selling one fourth of the material at a loss of 20% = (1/4) * 600 * (80/100) = Rs. 120 Price Received by remaining material at a gain of 10% = (3/4) * 600 * (110/100) = Rs. 495 [Note: 1-(1/4) = 3/4] Total Selling Price = 120 + 465 = Rs. 615 Profit = 615 – 600 = 15 beginaligned Profit% = left( fracGainCost * 100 right)% \ = left( frac15600 * 100 right)% \ = frac52% = 2frac12% endaligned 2. A man gains 20% by selling an article for a certain price. If he sells it at double the price, the percentage of profit will be. 130% 140% 150% 160% Answer: Option B Explanation: Let the C.P. = x, Then S.P. = (120/100)x = 6x/5 New S.P. = 2(6x/5) = 12x/5 Profit = 12x/5 – x = 7x/5 Profit% = (Profit/C.P.) * 100 => (7x/5) * (1/x) * 100 = 140 % 3. A man buys an article for Rs. 27.50 and sells it for Rs 28.60.

But I thought to try a new. Let us see whether you are comfortable or not. Dont mind. Given that “cp of 12 pens = sp of 15 pens” ==> cp of 1 pen = sp of 15 pens / 12 ==> cp of 1 pen = sp of 5/4 pens ==> cp of 1 pen = sp of 1 pen + sp of (1/4th part of the pen) ==> the sp of 1 pen is less than cp of 1 pen by “sp of 1/4th part of pen” ( which is loss on one pen, since SP<CP) That implies, Loss % = [sp of 1/4 pens] / [cp of 1 pen] * 100 = [sp of 1/4 pens] / [ sp of 5/4 pens] * 100 = 1/4 divided by 5/4 * 100 = 1/4 * 4/5 * 100 = 20 % What will be the profit if man sold 12 pens for the CP of 15 pens?
