If the profit on selling an article is 20% of its selling price, what is the actual profit percent on cost price?
Answer:
25%
Let SP = 100. Profit = 20. CP = SP - Profit = 100 - 20 = 80. Actual Profit % = (Profit / CP) * 100 = (20 / 80) * 100 = 25%.

A shopkeeper cheats to the extent of 20% while buying and 20% while selling by using false weights. His total gain percent is:
Answer:
44%
When cheating in both buying and selling, the effective profit is calculated by successive percentage formula: 20 + 20 + (20*20)/100 = 44%.

A man buys 12 pens for Rs. 10 and sells 10 pens for Rs. 12. His gain percent is:
Answer:
44%
CP of 1 pen = 10 / 12 = Rs. 5/6. SP of 1 pen = 12 / 10 = Rs. 6/5. Profit = 6/5 - 5/6 = (36 - 25) / 30 = 11 / 30. Profit % = ((11/30) / (5/6)) * 100 = (11 / 25) * 100 = 44%.

The single discount equivalent to two successive discounts of 30% and 10% is:
Answer:
37%
Using A + B - AB/100: 30 + 10 - (30 * 10) / 100 = 40 - 3 = 37%.

An article is sold at a certain price. If it is sold at 3/4 of that price, there is a loss of 10%. Find the profit percent when sold at the original price.
Answer:
20%
Let original SP be x. New SP = 0.75x. Loss = 10%, so New SP = 90% of CP. 0.75x = 0.90 * CP => CP = 0.75x / 0.90 = x / 1.2. Original Profit = x - CP = x - (x / 1.2) = 0.2x / 1.2. Profit % = ((0.2x / 1.2) / (x / 1.2)) * 100 = 20%.
4356
By selling 100 pens, a shopkeeper gains the selling price of 40 pens. Find his gain percent.
Answer:
66.66%
Let SP of 1 pen = 1. Total SP = 100. Gain = 40. CP = SP - Gain = 100 - 40 = 60. Gain % = (Gain / CP) * 100 = (40 / 60) * 100 = 66.66%.
4357
If selling price of an article is 4/3 of its cost price, the profit in the transaction is:
Answer:
33.33%
SP = (4/3)CP. Profit = SP - CP = (4/3)CP - CP = (1/3)CP. Profit % = (Profit / CP) * 100 = (1/3) * 100 = 33.33%.
4358
A man sells a car to his friend at a 10% loss. If the friend sells it for Rs. 54000 and gains 20%, the original cost price of the car was:
Answer:
Rs. 50000
Friend's SP = 54000. Friend's CP = 54000 / 1.20 = 45000. Man's SP = 45000. Man sold at 10% loss, so Man's CP = 45000 / 0.90 = Rs. 50000.
4359
A machine was sold at a gain of 10%. Had it been sold at Rs. 80 less, the seller would have lost 10%. What was the cost price of the machine?
Answer:
Rs. 400
The difference between 10% gain and 10% loss is 20% of the cost price. 20% of CP = Rs. 80. CP = (80 / 20) * 100 = Rs. 400.
4360
A merchant marks his goods up by 50% and then offers a discount on the marked price. If he wants to earn a profit of 20%, what should be the discount percentage?
Answer:
20%
Let CP = 100. MP = 150. Desired SP = 120. Discount = MP - SP = 150 - 120 = 30. Discount % = (30 / 150) * 100 = 20%.
