An item is sold at a profit of 10%. If it had been sold for Rs. 60 more, the profit would have been 15%. Find the cost price of the item.
Answer:
Rs. 1200
Let the Cost Price (CP) be x. The difference in the profit percentages is 15% - 10% = 5%. This 5% difference in profit corresponds directly to the Rs. 60 difference in the selling price. Therefore, 5% of CP = 60. So, (5 / 100) * x = 60. x = 60 * (100 / 5) = Rs. 1200.

A person sold two phones for Rs. 5000 each. On one, he gained 20% and on the other, he lost 20%. What is his overall profit or loss percentage?
Answer:
4% loss
When two items are sold at the same Selling Price and one is sold at a gain of x% and the other at a loss of x%, there is always an overall loss. The overall loss percentage is calculated by the formula (x^2) / 100. Here, x = 20, so overall loss % = (20^2) / 100 = 400 / 100 = 4% loss.

A shopkeeper marks his goods 20% above the cost price and allows a discount of 10%. Find his net profit percentage.
Answer:
8%
Let the Cost Price (CP) be Rs. 100. The Marked Price (MP) is 20% above CP, so MP = Rs. 120. He gives a 10% discount on the MP. Discount = 10% of 120 = Rs. 12. Selling Price (SP) = MP - Discount = 120 - 12 = Rs. 108. Net Profit = SP - CP = 108 - 100 = Rs. 8. Net profit percentage = (8 / 100) * 100 = 8%.

If the cost price of 20 tables is equal to the selling price of 25 tables, what is the loss percentage?
Answer:
20%
Let the Cost Price (CP) of 1 table be Rs. 1. The CP of 25 tables is Rs. 25. The Selling Price (SP) of 25 tables is equal to the CP of 20 tables, which is Rs. 20. Loss = CP - SP = 25 - 20 = Rs. 5. Loss percentage = (Loss / CP) * 100 = (5 / 25) * 100 = 20%.
4505
The cost price of 15 articles is equal to the selling price of 12 articles. Find the profit percentage.
Answer:
25%
Let the Cost Price (CP) of each article be Re. 1. Then, the CP of 12 articles is Rs. 12. The Selling Price (SP) of 12 articles equals the CP of 15 articles, which is Rs. 15. The profit on 12 articles is SP - CP = 15 - 12 = Rs. 3. The profit percentage = (Profit / CP) * 100 = (3 / 12) * 100 = 25%.
4506
If selling an item for Rs. 630 results in a loss of 10%, what is the cost price of the item?
Answer:
Rs. 700
A loss of 10% means the item was sold at 90% of its Cost Price (CP). Let CP be x. Therefore, 90% of x = 630. This gives 0.90 * x = 630, or x = 630 / 0.90 = 700. The cost price of the item is Rs. 700.
4507
An article is bought for Rs. 800. At what price should it be sold to gain 15%?
Answer:
Rs. 920
The Cost Price (CP) is Rs. 800 and the desired profit percentage is 15%. The Selling Price (SP) formula is SP = CP * (1 + Profit%/100). Thus, SP = 800 * (1 + 15/100) = 800 * 1.15 = Rs. 920. The article must be sold for Rs. 920.
4508
By selling a watch for Rs. 1440, a man earns a profit of 20%. What was the cost price of the watch?
Answer:
Rs. 1200
Let the Cost Price (CP) be x. A 20% profit means the Selling Price (SP) is 120% of the CP. So, 1.20 * x = 1440. Solving for x, we get x = 1440 / 1.20 = 144000 / 120 = Rs. 1200. Therefore, the cost price of the watch was Rs. 1200.
4509
A man purchased a bicycle for Rs. 1200 and sold it for Rs. 900. Find his loss percentage.
Answer:
25%
First, determine the loss by subtracting the Selling Price (SP) from the Cost Price (CP). Loss = CP - SP = 1200 - 900 = Rs. 300. The loss percentage is calculated on the Cost Price using the formula: (Loss / CP) * 100. Thus, Loss % = (300 / 1200) * 100 = 25%.
4510
A shopkeeper buys an article for Rs. 500 and sells it for Rs. 600. What is his profit percentage?
Answer:
20%
To find the profit percentage, first calculate the actual profit by subtracting the Cost Price (CP) from the Selling Price (SP). Profit = SP - CP = 600 - 500 = Rs. 100. The profit percentage is calculated on the Cost Price using the formula: (Profit / CP) * 100. Therefore, Profit % = (100 / 500) * 100 = 20%.
