Profit, Loss and Discount Questions
D
Correct answer
Explanation
Marked price per article is Rs. 100. Three articles sold for Rs. 274.50, so selling price per article = 274.50/3 = Rs. 91.50. Discount per article = 100 - 91.50 = Rs. 8.50. Discount percentage = (8.50/100) × 100 = 8.5%. The other options (7%, 7.5%, 8%) don't match this calculation.

Rs. 57000
D
Correct answer
Explanation
Let CP = x. First article SP = 1.15x, second SP = 1.15x + 5700. Total CP = 2x, total SP = 2.3x + 5700. Profit = 0.3x + 5700 = 0.2(2x) = 0.4x. Solving gives 0.1x = 5700, so x = 57000.
D
Correct answer
Explanation
Selling price = Rs 840 at 20% profit. Cost price = 840/1.2 = Rs 700. Option D matches.
C
Correct answer
Explanation
Let SP of 1m cloth = x. Total SP = 15x. Profit = SP of 5m = 5x. CP = 15x - 5x = 10x. Profit% = (5x/10x) × 100 = 50%.

B
Correct answer
Explanation
Let CP = x. SP at 25% profit = 1.25x. New CP = 0.8x (20% loss), new SP = 1.25x - 1050, which gives 30% profit on 0.8x. So 1.25x - 1050 = 1.3 × 0.8x = 1.04x. Therefore 0.21x = 1050, x = 1050/0.21 = 5000. Cost price is Rs. 5000.
D
Correct answer
Explanation
When selling at Rs. 900 with 20% profit, cost price = 900/1.20 = Rs. 750. At Rs. 975 selling price, profit = 975 - 750 = Rs. 225. Profit percentage = (225/750) × 100 = 30%. The key is to first find the cost price from the original transaction, then calculate the new profit percentage.

B
Correct answer
Explanation
Let cost prices be x and y with x + y = 2205. Selling prices: 1.2x (20% profit) and 0.85y (15% loss). Total profit 8%: 1.2x + 0.85y = 1.08 × 2205 = 2381.4. Solving: 1.2x + 0.85(2205 - x) = 2381.4 gives x = 1449, y = 756. Option B is correct.

Rs.756
C
Correct answer
Explanation
Let CP = x. Profit at 856 = 856 - x. Loss at 520 = x - 520. Given: 856 - x = 2(x - 520). Solving: 856 - x = 2x - 1040, so 3x = 1896 and x = 632. Verify: Profit = 224, Loss = 156, and 224 = 2 × 156.

C
Correct answer
Explanation
From first condition: 0.05SP = 0.08CP, so CP/SP = 5/8. From second: 0.2SP = 0.3CP + 130. Substituting SP = (8/5)CP: 0.2 × (8/5)CP = 0.3CP + 130, so 0.32CP - 0.3CP = 130, giving CP = 6500.
B
Correct answer
Explanation
Let CP = x. Profit percentage = x (numerical value of cost price). So profit = x% of CP = x × x / 100. Selling Price = CP + Profit = x + x²/100 = 75. This gives the quadratic equation x² + 100x - 7500 = 0. Solving: x = [-100 ± √(10000 + 30000)] / 2 = [-100 ± √40000] / 2 = [-100 ± 200] / 2. Taking positive value: x = (100)/2 = 50. Verification: CP = 50, profit = 50% of 50 = 25, SP = 50 + 25 = 75. The claimed answer B (50) is correct.
C
Correct answer
Explanation
Let MP = M. Selling at 80% gives loss of 10%, so 0.8M = 0.9CP (CP = cost price). This gives CP/M = 8/9. Selling at 95%: SP = 0.95M. Profit% = (SP - CP)/CP × 100 = (0.95M - 0.888...M)/(0.888...M) × 100 = 6.875%. The key is finding the CP to MP relationship first.

B
Correct answer
Explanation
Let water added = w liters. Total mixture = 15+w liters. To get 25% profit selling at CP of pure milk, he must sell 15+w liters at price of 15 liters. So (15+w) should equal 125% of 15 (since profit = 25%). 15+w = 1.25×15 = 18.75. Therefore w = 3.75 liters.

A
Correct answer
Explanation
Let CP = x. Original SP at 10% loss = 0.9x. New CP = 0.95x (5% less). New SP = 0.9x + 312. At 5% gain: New SP = 1.05 × 0.95x = 0.9975x. Equating: 0.9x + 312 = 0.9975x, giving 312 = 0.0975x, so x = 3200. Option A matches. Options B, C, and D don't satisfy the profit/loss conditions.
C
Correct answer
Explanation
Let CP = 100. Desired SP for 19% gain = 119. With markup of m% and 15% discount: 0.85(100+m) = 119. Solving: 85 + 0.85m = 119, so 0.85m = 34, giving m = 40. Option C matches. To verify: Mark up by 40% (MP = 140), give 15% discount (SP = 0.85 × 140 = 119), which is 19% profit on CP of 100. Options A, B, and D don't yield 19% profit.
B
Correct answer
Explanation
Let cost price be x. Profit = Selling Price - Cost Price = 75 - x. Profit percent = (Profit/Cost Price) × 100 = ((75-x)/x) × 100 = x. Solving: x² + 100x - 7500 = 0. Using quadratic formula: x = 50 or x = -150. Rejecting negative value, CP = 50. Verifying: 50% profit on Rs.50 gives Rs.75 selling price.
