The marked price of an article is 50% above cost price. When marked price is increased by 20% and selling price is increased by 20%, the profit doubles. What was original marked price if original CP is Rs. 100?
Answer:
Rs. 150
CP = 100. Marked Price is 50% above CP, so MP = 150. (The rest of the problem confirms properties, but the question explicitly asks for original marked price based on the initial statement).

A person bought an article and sold it at a loss of 10%. If he had bought it for 20% less and sold it for Rs. 55 more, he would have made a profit of 40%. The cost price of the article is:
Answer:
Rs. 250
Let CP = 100x. First SP = 90x. New CP = 80x. New SP = 80x * 1.40 = 112x. The difference in SP is 112x - 90x = 22x. We are given 22x = 55. So, x = 55 / 22 = 2.5. Original CP = 100x = 100 * 2.5 = Rs. 250.

A shopkeeper mixes two types of sugar, 15 kg of type A at Rs. 40/kg and 25 kg of type B at Rs. 60/kg. He sells the mixture at Rs. 55/kg. What is his profit percentage?
Answer:
4.7%
Total CP = (15 * 40) + (25 * 60) = 600 + 1500 = Rs. 2100. Total amount = 40 kg. Total SP = 40 * 55 = Rs. 2200. Profit = 2200 - 2100 = 100. Profit % = (100 / 2100) * 100 = 100 / 21 ≈ 4.76%.

A reduction of 20% in the price of salt enabled a shopper to buy 4 kg more for Rs. 100. What is the reduced price of salt per kg?
Answer:
Rs. 5
20% of Rs. 100 is Rs. 20. The shopper buys 4 kg more with this Rs. 20. Therefore, the reduced price per kg = 20 / 4 = Rs. 5.

The cost price of two dozen apples is Rs. 300. After selling 18 apples at the rate of Rs. 15 each, the shopkeeper reduced the rate to Rs. 10 each. What is the total profit or loss?
Answer:
Rs. 30 profit
CP of 24 apples = Rs. 300. SP of 18 apples = 18 * 15 = 270. SP of the remaining 6 apples = 6 * 10 = 60. Total SP = 270 + 60 = 330. Profit = 330 - 300 = Rs. 30.

A shopkeeper earns a profit of 12% on selling a book at a 10% discount on the printed price. The ratio of the cost price and printed price of the book is:
Answer:
45:56
Let Printed Price (MP) be 100. Discount = 10%, so SP = 90. Profit is 12%, so SP = 112% of CP. 1.12 * CP = 90 => CP = 90 / 1.12 = 9000 / 112 = 1125 / 14. Ratio of CP to MP = (1125 / 14) : 100 = 1125 : 1400. Dividing both by 25 gives 45 : 56.

If an article is sold at a gain of 5% instead of being sold at a loss of 5%, one gets Rs. 5 more. What is the cost price of the article?
Answer:
Rs. 50
Difference between 5% gain and 5% loss is 10% of CP. Therefore, 10% of CP = 5. CP = (5 / 10) * 100 = Rs. 50.

By selling 12 toffees for a rupee, a man loses 20%. How many for a rupee must he sell to get a gain of 20%?
Answer:
8
SP of 1 toffee = 1/12. At 20% loss, SP = 80% of CP. So, CP = (1/12) / 0.8 = 1/9.6. For 20% gain, new SP = 1.20 * CP = 1.20 * (1/9.6) = 1/8. This means he must sell 8 toffees for a rupee.

An article is sold at a loss of 10%. Had it been sold for Rs. 9 more, there would have been a gain of 12.5%. The cost price of the article is:
Answer:
Rs. 40
The change from a 10% loss to a 12.5% gain represents a total of 10% + 12.5% = 22.5% of CP. So, 22.5% of CP = 9. CP = (9 / 22.5) * 100 = 900 / 22.5 = Rs. 40.

A dealer marks his goods 20% above their cost price. He then allows some discount on it and makes a profit of 8%. Find the rate of discount.
Answer:
10%
Let CP = 100. MP = 120. Desired profit is 8%, so SP = 108. Discount given = MP - SP = 120 - 108 = 12. Discount % = (Discount / MP) * 100 = (12 / 120) * 100 = 10%.
