A dealer offers a cash discount of 20% and still makes a profit of 20%. If the cost price of an item is Rs. 400, what is its marked price?
Answer:
Rs. 600
CP = 400. Desired SP for 20% profit = 400 * 1.20 = 480. Since a 20% discount is offered, SP = 80% of MP. So, 0.8 * MP = 480 => MP = 480 / 0.8 = Rs. 600.

A discount of 15% on one article is the same as a discount of 20% on another article. The costs of the two articles can be:
Answer:
Rs. 80, Rs. 60
Let the prices be x and y. 15% of x = 20% of y. So, 15x = 20y => x/y = 20/15 = 4/3. Checking the options, 80/60 = 4/3.

By selling an umbrella for Rs. 300, a shopkeeper gains 20%. To gain 30%, he should sell it for:
Answer:
Rs. 325
CP = 300 / 1.20 = Rs. 250. For a 30% gain, SP = 1.30 * 250 = Rs. 325.

A radio is sold for Rs. 990 at a profit of 10%. What would have been the actual profit or loss on it, had it been sold for Rs. 890?
Answer:
Rs. 10 loss
SP = 990. Profit = 10%. CP = 990 / 1.10 = 900. If SP = 890, then Loss = CP - SP = 900 - 890 = Rs. 10.
4365
A shopkeeper expects a profit of 15%. If his weekly sale was Rs. 230, what was his profit?
Answer:
Rs. 30
Let CP be x. SP = x + 0.15x = 1.15x. 1.15x = 230 => x = 230 / 1.15 = 200. Profit = 230 - 200 = Rs. 30.

The marked price of a fan is Rs. 1500. It is available at a discount of 20%. Find the selling price.
Answer:
Rs. 1200
Discount = 20% of 1500 = 300. Selling Price = MP - Discount = 1500 - 300 = Rs. 1200.
4367
A man sold two articles for Rs. 2400 each. On one he gained 20% and on the other he lost 20%. His net loss in the transaction is:
Answer:
Rs. 200
Loss % = (20^2)/100 = 4%. Total SP = 2400 + 2400 = 4800. Since 96% of CP = 4800, CP = 5000. Loss = CP - SP = 5000 - 4800 = Rs. 200.
4368
A dishonest dealer uses a 900 gram weight instead of 1 kg and sells rice at its cost price. His profit percent is:
Answer:
11.11%
Profit % = (Error / True Value - Error) * 100 = (100 / 900) * 100 = 11.11%.
4369
A tradesman marks his goods at 20% above the cost price and allows a discount of 10%. What is his profit percent?
Answer:
8%
Let CP = 100. MP = 120. Discount = 10% of 120 = 12. SP = 120 - 12 = 108. Profit = 108 - 100 = 8. Profit % = 8%.

If the CP of 50 oranges is equal to the SP of 40 oranges, then the profit percent is:
Answer:
25%
Let CP of 1 orange = Rs. 1. Total CP of 40 oranges = Rs. 40. SP of 40 oranges = CP of 50 oranges = Rs. 50. Profit = 50 - 40 = 10. Profit % = (10 / 40) * 100 = 25%.
