Question 1
In a certain store, the profit percentage is 320% of the cost price. If the cost price increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?
30%
70%
100%
250%
Good Job!
Oops!
Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420. New C.P. = 125% of Rs. 100 = Rs. 125 New S.P. = Rs. 420. Profit = Rs. (420 – 125) = Rs. 295. Required percentage =[(295/420) * 100] % = 1475/21 % =70 %

Question 2
If the selling price is doubled, the profit triples. Find the profit percent.
66 2/3
100
105 1/3
120
Let C.P. be Rs. x and S.P. be Rs. y. Then, 3(y – x) = (2y – x) =>y = 2x. Profit = Rs. (y – x) = Rs. (2x – x) = Rs. x. Profit % = [x/x * 100]%= 100%
Question 3
The list price of an article is Rs. 160 and a customer buys it for Rs. 122.40 after two successive discounts. If the first discount is 10%, then the second discount is
12%
10%
14%
15%
SP after a discount of 10% = (160*90) / 100 = Rs. 144 Second discount = 144 – 122.40 = Rs. 21.6 If the second discount be x% then x= 15%
Question 4
A tradesman sold an article at a loss of 20%. If the selling price had been increased by Rs. 100, there would have been a gain of 5%. The cost price of the article (in Rs.) was
200
400
500
C. P. of article = Rs. X ∴ First SP = 80x/100 = Rs. 4x/5 Case II ⇒ 5x = 2000 ⇒ x = 2000/5 = Rs. 400
Question 5
The price of an article is first decreased by 20% and then increased by 30%. If the resulting price is Rs. 416, the original price of the article is
Rs. 350
Rs. 405
Rs. 400
Rs. 450
let x be the price so, after the first decrease in price = x - x *20/100 = 0.8x after second increase in price = 0.8x + 0.8*30/100 =1.04x so, 1.04x = 416 x=400.
Question 6
If the compound interest on a certain sum for two years at 12% per annum is Rs. 2544 the simple interest on it at the same rate for 2 years will be
Rs. 2400
Rs. 2500
Rs. 2480
Rs. 2440

Question 7
Three independent strategies A, B, and C have been initiated for cost-cutting in a company producing respectively 30%, 40%, and 10% savings. Assuming that they operate independently, what is the net saving achieved?
56%
64%
62.2%
68%
If initial cost is Rs 100, then Final cost will be 100*0.7*0.6*0.9 = Rs. 37.8 savings = 100-37.8=62.2 so 62.2%
Question 8
If after successive discounts of 20% and 25/4% on the marked price of an article, a trader gets 20% profit on the cost price, then by what percent is the marked price above the cost price?
60%
65%
55%
50%
Let the market price be RS 100. Then after the first discount, S.P becomes 80 and after another discount it becomes Rs. 75. so S.P = 75. now with this S.P he has made a profit of 20% and hence the C.P = (75/120)*100 = 62.5 so percentage change with respect to market price is = (37.5/62.5)*100 giving 60%
Question 9
The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is
15
16
18
25
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x. S.P. of x articles = Rs. 20. Profit = Rs. (20 - x). (20 - x)/x * 100 = 25 2000 - 100x = 25x 125x = 2000 x = 16.
Question 10
A grocer has a sale of Rs. 6435, Rs. 6927, Rs. 6855, Rs. 7230 and Rs. 6562 for 5 consecutive months. How much sale must he have in the sixth month so that he gets an average sale of Rs. 6500?
Rs. 4991
Rs. 5991
Rs. 6001
Rs. 6991
Total sale for 5 months = Rs. (6435 + 6927 + 6855 + 7230 + 6562) = =Rs. 34009. Required sale = Rs. [ (6500 x 6) - 34009 ] = Rs. (39000 - 34009) = Rs. 4991.
