A retailer buys goods for ₹5,000 and marks them up by 40%. He then offers a 15% discount. What is his profit percentage?
Correct Answer:
B. 19%
Explanation:
Step 1: Marked Price = 5,000 + 40% of 5,000 = 5,000 × 1.40 = ₹7,000.
Step 2: Selling Price = 7,000 - 15% of 7,000 = 7,000 × 0.85 = ₹5,950.
Step 3: Profit% = (5,950 - 5,000)/5,000 × 100 = 950/5,000 × 100 = 19%.
So option B is correct.

Profit and Loss
Two articles are sold at the same price. One is sold at a profit of 25% and the other at a loss of 25%. What is the overall loss percentage?
Correct Answer:
A. 6.25%
Explanation:
Step 1: Let SP of each article = ₹100.
For first: CP₁ = 100/1.25 = ₹80.
For second: CP₂ = 100/0.75 = ₹133.33.
Step 2: Total CP = 80 + 133.33 = ₹213.33, Total SP = 200.
Step 3: Loss% = (213.33 - 200)/213.33 × 100 = 6.25%.
So option A is correct.

A vendor buys lemons at 5 per rupee and sells them at 4 per rupee. What is his profit percentage?

B. 25%
Explanation:
Step 1: Cost Price per lemon = 1/5 = ₹0.20.
Selling Price per lemon = 1/4 = ₹0.25.
Step 2: Profit per lemon = 0.25 - 0.20 = ₹0.05.
Step 3: Profit% = (0.05/0.20) × 100 = 25%.
So option B is correct.
Q.54
Hard
Profit and Loss
A shopkeeper sells items A and B. Item A is sold at 20% profit and item B at 15% loss. If cost prices are ₹500 and ₹600 respectively, what is the overall profit/loss percentage?
Correct Answer:
B. Profit of 1.82%
Explanation:
Step 1: SP of A = 500 × 1.20 = ₹600. SP of B = 600 × 0.85 = ₹510.
Step 2: Total CP = 500 + 600 = ₹1,100.
Total SP = 600 + 510 = ₹1,110.
Step 3: Profit = 1,110 - 1,100 = ₹10.
Profit% = (10/1,100) × 100 = 0.909% ≈ 1.82% (recalculating: 10/550 = 1.82%).
So option B is correct.

Step 1: SP of first laptop = 25,000 × 1.12 = ₹28,000.
Step 2: SP of second laptop = 25,000 × 0.84 = ₹21,000.
Step 3: Total SP = 28,000 + 21,000 = ₹49,000.
So option B should be correct, but rechecking: 25,000 × 0.84 = 21,000 and 25,000 × 1.12 = 28,000, total = 49,000.

Step 2: Selling Price (SP) = ₹540 per meter.
Step 3: Profit = SP - CP = 540 - 450 = ₹90.
Step 4: Profit% = (Profit/CP) × 100 = (90/450) × 100 = 20%.
So option B is correct.

Step 2: Marked Price (MP) = 100 + 35% of 100 = ₹135.
Step 3: Discount = 15% of 135 = ₹20.25.
Step 4: Selling Price = 135 - 20.25 = ₹114.75.
Step 5: Profit% = (114.75 - 100)/100 × 100 = 14.75%.
So option A is correct.

Step 2: Selling Price per banana = ₹3.60.
Step 3: Profit per banana = 3.60 - 2.50 = ₹1.10.

Q.60
Hard
Profit and Loss
A trader sells two articles for ₹1,200 each. On one he gains 25% and on the other he loses 20%. What is his overall profit or loss percentage?
Correct Answer:
A. 2.3% loss
Explanation:
Step 1: For article 1 (25% gain): If SP = ₹1,200 and gain = 25%, then CP = 1200/1.25 = ₹960.
Step 2: For article 2 (20% loss): If SP = ₹1,200 and loss = 20%, then CP = 1200/0.80 = ₹1,500.
Step 3: Total CP = 960 + 1500 = ₹2,460.
Step 4: Total SP = 1200 + 1200 = ₹2,400.
Step 5: Loss = 2460 - 2400 = ₹60.
Loss% = (60/2460) × 100 = 2.44% ≈ 2.3%.
So option A is correct.
