16. The profit earned by selling an article for Rs 900 is double the loss incurred when the same article is sold for Rs 450 .At what price should the article be sold to make 25% profit? Difference between the two prices : 900 – 450 = 450 let us take 2/3 of this (because the ratio of profit and loss is 2:1) 450 * 2/3 = 300 COST = 900 – 300 =600 TO EARN 25% PROFIT : 600 * 1.25 = 750

Let us assume that the sale price is 100 each. Cost of the two flats is : 1. in profit 100 * 100/116 =86.21 2. that in loss : 100 * 100/84=119.05 NOW ADD THESE : 86.21+119.05=205.26 thus we can see that actually there is a loss of 5.26 on cost of 205.26. the loss in % is : 5.26/ 205.26 * 100 = 2.56 % SHORT CUT = multiply : 16% with 16% , you get 2.56%. 2.56/100 * 2*675,958 = loss of 34609 answer ALWAYS USE SHORTCUT FOR SUCH QUESTION SQUARE UP THE % PROFIT & LOSS AND GET ANSWER)

Suppose original price = 100 reduced by 20% = 80 NOW WE HAVE TO RESTORE IT we have to increase 20 to restore 20 / 80 * 100 = 25% answer SHORTCUT : (20 / (100-20)*100 ) (IF REDUCTION RATE IS X% : X/(100-X) * 100 )

29. Sam purchased 20 dozens of toys at the rate of 375 Rs per dozen .He sold each one of then at the rate of Rs 33.What was his percentage profit? Total cost = 375 * 20 = 7500 revenue : 240 * 33 = 7920 profit = 420 profit in % 420/7500 * 100 = 5.6%

30. Two third of consignment was sold at a profit of 5% and the remainder at a loss of 2%.If the total profit was Rs 400,the value of the consignment was? For such questions, start with your own assumptions. Since you have to calculate 2/3rd, so take up multiple of 3, let us say 300 Let us assume that the value of consignment was 300 200 sold for 5% profit = 10 100 sold for loss of 2% = -2 net result = +8 thus value of consignment = 400/8 * 300 = 15000 answer

31. Kunal bought a suitcase with 15% discount on the labelled price. He sold the suitcase for Rs 2880 with 20% profit on the labelled price .At what price did he buy the suitcase? Let us assume the label price = 100 his purchase price = 85 his sale price 100 + 20 = 120 actual cost = 85/120 * 2880 = 2040 answer

32. A tradesman gives 4% discount on the marked price and gives an article free for buying every 15 articles and thus gains 35%.The marked price is above the cost price by Suppose a customer takes away 16 items costing 10 each, cost = 160 price collected = 160 + 35% = 216 per unit price 216/15 = 14.4 this is 96% of the marked price marked price is : 100/96 * 14.4 = 15 thus marked price is 50% above the cost price (cost 10, marked price 15, so ratio is 2:3)

33. By selling 33m of cloth ,one gains the selling price of 11m.Find the gain percent? Suppose price of cloth is 1 per meter Total sale price = 33 Total profit = 11 cost = 33-11 = 22 profit in % = 11/22 *100 = 50% (remember, profit has to be calculated on cost, not on the print price).

34. The price of a jewel, passing through three hands, rises on the whole by 65%.if the first and second sellers earned 20% and 25% profit respectively,find the percentage profit earned by the third seller? Let us assume the cost of 1 st seller = 100 he sells it at : 120 2 nd seller sells it at : 120+25% = 150 the 3 rd seller sells it at 165 (given in question) so profit of 3 rd seller is (165-150) = 15 which is 10% of his cost (his cost is 150). answer

35. When a producer allows 36% commission on the retail price of his product ,he earns a profit of 8.8%.what would be his profit percent if the commission rate is changed to 12% Let us assume that the sale price is 1000 commission : 360 net money received = 640 less – profit = 88 = 552 cost = 552 reduction in commission = .24 *1000 =240 his new profit = 88+240 =328 profit in % = 328/552 * 100 = 59. 42% answer
