B
Correct answer
Explanation
Selling price after 40% profit on Rs.180 is Rs.252 (180 × 1.4). Since this is after 25% discount, marked price = 252 ÷ 0.75 = 336. The relationship is SP = MP × (1 - discount%).
B
Correct answer
Explanation
If CP = 80% of SP, then CP = 0.8 × SP. Profit = SP - CP = SP - 0.8SP = 0.2SP. Profit percent = (Profit/CP) × 100 = (0.2SP / 0.8SP) × 100 = (1/4) × 100 = 25%. Option B (25) is correct. Options A (20), C (30), and D (28) are incorrect.
B
Correct answer
Explanation
Discount percentage is calculated on the marked price. The discount amount is Rs. 192 on a marked price of Rs. 960. Therefore, discount percentage = (192/960) × 100 = 20%. Option B is correct. This is a straightforward percentage calculation.

$Rs. 612$
D
Correct answer
Explanation
Apply successive discounts to find the selling price. First discount of 15% on Rs. 800 gives Rs. 680. Then apply 10% discount on Rs. 680: 680 × 0.90 = Rs. 612. The key is applying discounts sequentially, not additively (15% + 10% = 25% would incorrectly give Rs. 600).

C
Correct answer
Explanation
Let CP of 1 article = 1, then CP of 140 articles = 140. Given SP of 125 articles = CP of 140 articles = 140. So SP of 1 article = 140/125 = 28/25. Profit on 1 article = SP - CP = 28/25 - 1 = 3/25. Profit percent = (Profit/CP) × 100 = (3/25)/1 × 100 = 12%.

B
Correct answer
Explanation
Let B's cost price = x. Then A's cost price = x + 50. A sells at 16% profit: 1.16(x + 50) = 1.16x + 58. B sells at 7% profit: 1.07x. Total profit = (1.16x + 58 + 1.07x) - (2x + 50) = 0.23x + 8 = 100. Solving: 0.23x = 92, x = 400. B's price is Rs. 400.

None of these
C
Correct answer
Explanation
If cost price = 100, marked price = 120 (20% more). After 20% discount, selling price = 120 × 0.8 = 96. Loss = 100 - 96 = 4 on CP of 100, which is 4% loss. Option C correctly states this result.

A
Correct answer
Explanation
Let shopkeeper's CP = x, so SP = x + 600. Man buys at x + 600, increases by 60% to get 1.6(x + 600), then gives 25% discount, so final SP = 0.75 × 1.6(x + 600) = 1.2x + 720. Man's profit = (1.2x + 720) - (x + 600) = 0.2x + 120. Given this equals shopkeeper's profit (600) plus 40, so 0.2x + 120 = 640, giving x = 2600. Option A matches this result.

None of these
A
Correct answer
Explanation
If CP = 95 and discount = 5%, then marked price = 95 × 1.10 = 104.5, not 110. But if marked price = 110 and discount = 5%, selling price = 110 × 0.95 = 104.5. Profit = 104.5 - 95 = 9.5, which is not 10% of 95 (which would be 9.5). Actually 9.5/95 = 0.1 = 10%. So this works. The calculation is: SP = MP × (1 - discount) = 110 × 0.95 = 104.5, and profit = 104.5 - 95 = 9.5, which is exactly 10% of 95.
B
Correct answer
Explanation
Cost price = 1/4 rupee per orange. Selling price = 1/5 rupee per orange. Loss = CP - SP = 1/4 - 1/5 = 1/20. Loss% = (1/20) / (1/4) × 100 = (1/20) × 4 × 100 = 20%. Option B is correct.
-
Rs 900
-
Rs 800
-
Rs 700
-
Rs 600
D
Correct answer
Explanation
Selling price after 10% discount = 90% of 800 = 720. This includes 20% profit, so 720 = 120% of CP. CP = 720/1.2 = 600. Option A would mean SP is 80% of CP (loss), Option B would mean SP = 90% of CP (loss), Option C would mean SP > CP (profit > 20%).

D
Correct answer
Explanation
Cost price = Rs 32 for 24 bananas, so CP per banana = 32/24 = 4/3. Revenue: 18 bananas at Rs 12/dozen = Rs 18, and 6 bananas at Rs 4/dozen = Rs 2. Total revenue = Rs 20. Loss = 32 - 20 = Rs 12. Loss% = 12/32 × 100 = 37.5%. Options A, B, C are incorrect loss percentage calculations.

-
$2.56% loss$
-
$4.68% gain$
C
Correct answer
Explanation
When selling two items at the same price, one at x% gain and the other at x% loss, the overall transaction always results in a loss of (x/10)^2%. Here x = 16, so loss = (16/10)^2 = 2.56%. The total selling price is Rs 4000, but the total cost price is higher (Rs 4105.60), resulting in a 2.56% loss. Option C is correct.
A
Correct answer
Explanation
Let CP = x. SP at 60% profit = 1.6x. Given: 1.6x = (1/3)x + 38. So 1.6x - 0.333x = 38, giving 1.267x = 38. Therefore x = 38/1.267 = 30. Option B (45) could result from misreading 'one third of CP' as 'one third of SP' in the equation.
C
Correct answer
Explanation
After first discount of 15%, price becomes 740 × 0.85 = 629. After second discount of x%, final price is 629 × (1 - x/100) = 566.10. Therefore 1 - x/100 = 566.10/629 = 0.9, which gives x/100 = 0.1, so x = 10. The second discount is 10%.
