Find the single discount equivalent to three successive discounts of 10%, 20%, and 25%.
Answer:
46%
Let MP = 100. After 10%, price = 90. After 20% on 90, price = 90 - 18 = 72. After 25% on 72, price = 72 - 18 = 54. The final price is 54, which means the total discount is 100 - 54 = 46%.

A merchant marks his goods at Rs. 450. After allowing a 20% discount, he earns a profit of 20%. The cost price of the goods is:
Answer:
Rs. 300
MP = 450. Discount = 20% of 450 = 90. SP = 450 - 90 = 360. Profit is 20%, meaning SP = 120% of CP. 1.20 * CP = 360 => CP = 360 / 1.2 = Rs. 300.

A trader marks up his goods by 25% and offers a 10% discount. Further, he uses a 900g weight instead of 1 kg. His overall profit percentage is:
Answer:
25%
Let true CP for 1000g be 100. He uses 900g, so his actual cost is 90. He marks up 1000g to 125, then gives a 10% discount on 125, so SP = 125 - 12.5 = 112.5. Profit = 112.5 - 90 = 22.5. Profit % = (22.5 / 90) * 100 = 25%.
4334
An article was sold at a 12% loss. Had it been sold for Rs. 63 more, the profit would have been 6%. Cost price of the article is:
Answer:
Rs. 350
The change in price represents a shift from 12% loss to 6% profit, which is a gap of 18% of CP. So, 18% of CP = 63. CP = (63 / 18) * 100 = Rs. 350.
4335
A manufacturer sells to a wholesaler at a profit of 10%. The wholesaler sells to a retailer at a profit of 20%. The retailer sells to a customer for Rs. 56100, earning a profit of 15%. The cost of manufacturing is:
Answer:
Rs. 40000
Let manufacturing cost be x. x * 1.10 * 1.20 * 1.15 = 56100. x * 1.518 = 56100. x = 56100 / 1.518 = Rs. 40000.
4336
A reduction of 20% in the price of apples enables a man to buy 10 kg more for Rs. 54. The reduced price per kg is:
Answer:
Rs. 1.08
20% of Rs. 54 is Rs. 10.8. This Rs. 10.8 allows him to buy the extra 10 kg. Reduced price per kg = 10.8 / 10 = Rs. 1.08.
4337
If the SP of 40 articles is equal to the CP of 50 articles, the profit percent is:
Answer:
25%
Let CP of 1 article = 1. CP of 40 articles = 40. SP of 40 articles = CP of 50 articles = 50. Profit = 50 - 40 = 10. Profit % = (10 / 40) * 100 = 25%.
4338
A man sells a book for Rs. 150 at a 20% profit. What was his cost price?
Answer:
Rs. 125
SP = 150. Profit = 20%, so SP is 120% of CP. 1.20 * CP = 150 => CP = 150 / 1.2 = 1500 / 12 = Rs. 125.
4339
A shopkeeper sells two articles at Rs. 1000 each. On one he gains 25% and on the other he loses 25%. His net loss in the transaction is:
Answer:
Rs. 133.33
Loss % = (25^2)/100 = 6.25% = 1/16. Total SP = 2000. SP is 15/16 of CP. So, (15/16) * CP = 2000 => CP = 32000 / 15 = 2133.33. Loss = CP - SP = 2133.33 - 2000 = Rs. 133.33.
4340
A trader marks his goods at 40% above the cost price and allows a discount of 25%. His profit percent is:
Answer:
5%
Let CP = 100. MP = 140. Discount = 25% of 140 = 35. SP = 140 - 35 = 105. Profit = 105 - 100 = 5. Profit % = 5%.
