If an article is sold at 19% profit instead of 12% profit, then the profit would be Rs. 105 more. What is the cost price?

A. Rs. 1505
B. Rs. 1510
C. Rs. 1500
D. Rs. 1490
E. None of these
Explanation:
Let the cost price of an article be Rs. x.
(19% of x) – (12% of x) = 105
19x/100 – 12x/100 = 105 => 7x = 105 * 100
=> x = 1500
Cost price = Rs. 1500

by
A shopkeeper loses 15%, if an article is sold for Rs. 102. What should be the selling price of the article to gain 20%?

A. Rs. 150
B. Rs. 144
C. Rs. 138
D. Rs. 132
E. None of these
Explanation:
Given that SP = Rs. 102 and loss = 15%
CP = [100(SP)]/(100 – l%) = (100 * 102)/85 = 20 * 6 = Rs. 120.
To get 20% profit, New SP = [(100 + p%)CP]/100 = (120 * 120)/100 = Rs. 144

A dishonest dealer professes to sell his goods at Cost Price but still gets 20% profit by using a false weight. What weight does he substitute for a kilogram?

A. 855 1/2 grams
B. 833 1/3 grams
C. 833 1/2 grams
D. 875 2/7 grams
Explanation:
If the cost price is Rs.100, then to get a profit of 20%, the selling price should be Rs.120.
If 120kg are to be sold, and the dealer gives only 100kg, to get a profit of 20%.
How many grams he has to give instead of one kilogram(1000 gm).
120 gm —— 100 gm

A shopkeeper buys mangoes at the rate of 4 a rupee and sells them at 3 a rupee. Find his net profit or loss percent?

A. 20%
B. 28%
C. 33 1/3 %
D. 35 2/7 %
Explanation:
The total number of mangoes bought by the shopkeeper be 12.
If he buys 4 a rupee, his CP = 3

A shopkeeper sells two articles at Rs.1000 each, making a profit of 20% on the first article and a loss of 20% on the second article. Find the net profit or loss that he makes?

by
A shopkeeper sells two articles at Rs.1000 each, making a profit of 20% on the first article and a loss of 20% on the second article. Find the net profit or loss that he makes?

A. neither profit nor loss
B. 3%
C. 5%
D. 4%
Explanation:
SP of first article = 1000
Profit = 20%
CP = (SP)*[100/(100+P)] = 5000/6 = 2500/3
SP of second article = 1000
Loss = 20%
CP = (SP)*[100/(100-L)] = 5000/4 = 1250
Total SP = 2000
Total CP = 2500/3 + 1250 = 6250/3
CP is more than SP, he makes a loss.
Loss = CP-SP = (6250/3)- 2000 = 250/3
Loss Percent = [(250/3)/(6250/3)]*100 =
0.04 * 100 = 4%
