Q.1 Loss on selling on object for Rs. 500 is equal to the profit gained if the object is sold for Rs.900. Find the original C.P. of the object.
If we are given two selling prices of which one is showing loss and other giving the profit, find out the difference and divide it in the ratio of loss and profit. Here the ratio was 1 : 1, so we divided 400 in 1 : 1
Q.2 A shopkeeper when sells on object for Rs. 900, then he faces loss which is equal to half of the profit gained if the object is sold for Rs. 1200. Find cost price.
C.P. = 900+100 or 1200 - 200
=Rs 1000
In this question, the ratio of loss and profit was 1 : 2 so, accordingly we divided the difference in the ratio 1 : 2 which gave us 100 and 200.
Q.3 A person gained Rs.50 more as profit from the amount he lost if he had sold it for Rs. 600, after selling it for Rs. 760. Find C.P.
C.P = 600 + 55 or 760 -105
=Rs. 655
Profit on 2nd S.P. will be Rs. 50 more than the loss on 1st S.P., So if we deduct Rs. 50 from difference, the remaining will be equal profit and loss so, either add 55 to 1st S.P. or deduct 105 from 2nd S.P.
Q.4 A shopkeeper sells an article at 20% profit. Had he purchased it at 10% less price and sold it at 30% profit, he would have charged Rs. 15 less for the article. Find original C.P. of the article.
We assume the C.P. = Rs. 100 and S.P. = Rs.120. (After 20% profit). After purchasing it for 10% less, the new C.P. becomes 90 and selling it at 30% profit gives now S.P. = Rs. 117. Difference is Rs. 15 which is 5 times of obtain difference. Original C.P. will also be 5 times of assumed C.P. = Rs.500
Q.5 A reduction of 20% in the cost price of sugar enables a house wife to buy 5kg. more sugar for Rs. 100. Find original cost price.
Original Price = 100/20 =Rs.51 Kg
20% can be written as 1/5. So, if the original price was 5, new price will be for. In the same way,old consumption will be 4 unit and new consumption will be 5 unit because decrease in price of the sugar will be directly proportional to the increase in consumption increase in consumption is 1 unit but actual increase is 5 Kg.
∴ Original consumption and new consumtion will also be 5 times i.e. 20 kg and 25 kg.
