A TV is purchased at Rs. 5000 and sold at Rs. 4000. Find the lost percent.
Answer:
20%
Loss = CP - SP = 5000 - 4000 = Rs. 1000. Loss % = (Loss / CP) * 100 = (1000 / 5000) * 100 = 20%.

Successive discounts of 10%, 12%, and 15% amount to a single discount of:
Answer:
32.68%
Let MP = 100. After 10% discount, price = 90. After 12% discount, price = 90 - (12% of 90) = 90 - 10.8 = 79.2. After 15% discount, price = 79.2 - (15% of 79.2) = 79.2 - 11.88 = 67.32. Total discount = 100 - 67.32 = 32.68%.

If the cost price of 12 pens is equal to the selling price of 8 pens, the gain percent is:
Answer:
50%
Let CP of 1 pen = Rs. 1. So, CP of 8 pens = Rs. 8. SP of 8 pens = CP of 12 pens = Rs. 12. Profit on selling 8 pens = 12 - 8 = Rs. 4. Gain % = (Profit / CP) * 100 = (4 / 8) * 100 = 50%.

A shopkeeper professes to sell his goods at cost price but uses a weight of 800 gm instead of 1 kg. Thus, he makes a profit of:
Answer:
25%
He delivers 800 gm but charges for 1000 gm. His actual cost is the price of 800 gm, and his profit is the equivalent of 200 gm. Profit % = (Error / True Value - Error) * 100 = (200 / 800) * 100 = 25%.

A man buys 10 articles for Rs. 8 and sells them at 8 for Rs. 10. Find his gain percent.
Answer:
56.25%
CP of 1 article = 8 / 10 = Rs. 0.80. SP of 1 article = 10 / 8 = Rs. 1.25. Profit = 1.25 - 0.80 = Rs. 0.45. Gain % = (Profit / CP) * 100 = (0.45 / 0.80) * 100 = (45 / 80) * 100 = 56.25%.

A loss of 19% gets converted into a profit of 17% when the selling price is increased by Rs. 162. The cost price of the article is:
Answer:
Rs. 450
The change in price from a 19% loss to a 17% profit represents a total change of 19% + 17% = 36% of the Cost Price (CP). So, 36% of CP = 162. CP = (162 * 100) / 36 = Rs. 450.

A shopkeeper bought 80 kg of sugar at Rs. 13.50 per kg and mixed it with 120 kg sugar at Rs. 16 per kg. If he is to make a profit of 16%, what should be the selling price per kg?
Answer:
Rs. 17.40
Total Cost Price = (80 * 13.50) + (120 * 16) = 1080 + 1920 = Rs. 3000. Total quantity = 80 + 120 = 200 kg. Cost Price per kg = 3000 / 200 = Rs. 15 per kg. To make a 16% profit, SP = 15 * 1.16 = Rs. 17.40 per kg.
4468
A tradesman marks his goods at such a price that after allowing a discount of 15%, he makes a profit of 20%. What is the marked price of an article whose cost price is Rs. 170?
Answer:
Rs. 240
CP = 170. Profit = 20%. SP = CP * 1.20 = 170 * 1.20 = Rs. 204. The dealer allows a 15% discount on the Marked Price (MP), so SP = 85% of MP. Therefore, 0.85 * MP = 204. MP = 204 / 0.85 = 240. The marked price is Rs. 240.
4469
If selling price is doubled, the profit triples. Find the profit percent.
Answer:
100%
Let original CP = x and original SP = y. Original profit = y - x. If SP is doubled, new SP = 2y. New profit = 2y - x. Given that new profit is triple the original profit: 2y - x = 3(y - x) => 2y - x = 3y - 3x => y = 2x. Original profit = 2x - x = x. Profit % = (Profit / CP) * 100 = (x / x) * 100 = 100%.

A man sold two steel chairs for Rs. 500 each. On one, he gains 20% and on the other, he loses 12%. How much does he gain or lose in the whole transaction?
Answer:
1.5% gain
Total SP = 500 + 500 = 1000. CP of first chair = 500 / 1.20 = 416.67. CP of second chair = 500 / 0.88 = 568.18. Total CP = 416.67 + 568.18 = 984.85. Since SP (1000) > Total CP (984.85), there is a gain. Gain = 1000 - 984.85 = 15.15. Gain % = (15.15 / 984.85) * 100 ≈ 1.5% gain.
