Profit, Loss and Discount Questions
C
Correct answer
Explanation
Let cost price be 100. Marked price is 50% more, so MP = 150. After 10% discount on marked price, selling price = 150 - 15 = 135. Profit = 135 - 100 = 35, which is 35% of cost price. Remember: discount is always applied on marked price, not cost price.
D
Correct answer
Explanation
Let CP = 5x and SP = 6x. Profit = SP - CP = x. Profit percentage = (Profit/CP) × 100 = (x/5x) × 100 = 20%. When given ratio of CP:SP, the profit percentage is (difference/CP) × 100.
B
Correct answer
Explanation
CP per chair = 5/9 Rs. SP per chair = 9/5 Rs. Profit per chair = (9/5) - (5/9) = 56/45 Rs. Profit% = (56/45)/(5/9) × 100 = (56/45)×(9/5)×100 = 224%.
A
Correct answer
Explanation
After 15% discount: 3000 × 0.85 = 2550. Final price after a% discount: 2550 × (1-a/100) = 2142. Solving gives 1 - a/100 = 0.84, so a = 16%.

A
Correct answer
Explanation
Let CP = 100. Marked price = 140 (40% more than CP). Discount of 40% means selling price = 60% of 140 = 84. So loss = CP - SP = 100 - 84 = 16. Loss percent = 16%. Options B and D incorrectly expect profit. Option C underestimates the loss.
A
Correct answer
Explanation
Gain = cost price of 20 metres when selling 50 metres. So gain on each metre = 20/50 = 2/5 of CP. Gain percent = (2/5) × 100 = 40%. When profit is expressed as 'gain equals CP of x units when selling y units', the gain percent is (x/y) × 100.
D
Correct answer
Explanation
Loss = Rs 10 - Rs 7 = Rs 3 per article. Loss percent = (Loss/CP) × 100 = (3/10) × 100 = 30%. When SP < CP, calculate loss percent on CP, not on SP.
A
Correct answer
Explanation
Selling 6 items gives profit equal to SP of 1 item. So SP × 6 - CP × 6 = SP × 1, which gives 5 SP = 6 CP, or SP/CP = 6/5. Profit% = (SP - CP)/CP × 100 = (6/5 - 1) × 100 = 1/5 × 100 = 20%.
B
Correct answer
Explanation
Discount = Marked Price - Selling Price = 7600 - 5472 = 2128. Discount percentage = (Discount/Marked Price) × 100 = (2128/7600) × 100 = 28%. The discount reduces the price from 7600 to 5472, which is exactly 28% off. Options A, C, and D are miscalculations of this percentage.
A
Correct answer
Explanation
First discount: 6800 × (1 - 0.12) = 6800 × 0.88 = 5984. Second discount: 5984 × (1 - 0.20) = 5984 × 0.80 = 4787.2. Alternatively: 6800 × 0.88 × 0.80 = 6800 × 0.704 = 4787.2. Successive discounts compound multiplicatively. Options B, C, and D are miscalculations.
D
Correct answer
Explanation
Let marked price = M. After 40% discount, selling price = 0.6M. This gives 25% profit, so 0.6M = 1.25 × Cost. Cost = 0.6M/1.25 = 0.48M. Without discount, selling price = M. Profit = (M - 0.48M)/0.48M × 100 = 0.52/0.48 × 100 = 108.33%.

C
Correct answer
Explanation
The correct answer is C. Let the cost price be x. The difference between 18% profit and 15% profit is 3% of x, which equals Rs. 960. So 0.03x = 960, giving x = 960 / 0.03 = Rs. 32,000. Options A, B, and D are incorrect calculations. The key insight is that the 3% difference in profit rates directly corresponds to the Rs. 960 difference in selling prices.
C
Correct answer
Explanation
Let CP = x. After 66.67% (2/3) gain: x × 5/3. After 37.5% (3/8) gain: (5x/3) × 11/8 = 55x/24 = 2200. Therefore x = 2200 × 24/55 = 960. Verify: 960 × 5/3 = 1600, then 1600 × 11/8 = 2200. Working backwards uses the same multipliers.

A
Correct answer
Explanation
Let CP = x. Original SP = 1.15x. New CP = 1.05x, new SP = 1.15x + 6. New profit = 10%, so (1.15x + 6)/(1.05x) = 1.10. This gives 1.15x + 6 = 1.155x, so 0.005x = 6, x = 1200. This profit and loss problem requires setting up equations with percentages and solving for the cost price.

C
Correct answer
Explanation
Selling price = Marked Price × (1 - Discount%). So 880 = MP × 0.88. Therefore MP = 880/0.88 = 1000. Option A (1100) and D (2100) don't satisfy the equation. Option B (2000) would give a selling price of 1760, not 880.
