Quantitative Aptitude - MCQ Practice Questions

SP = MP × 0.8 × 0.85 = MP × 0.68 = 1,292. MP = 1,$\frac{292}{0}$.68 = ₹1,900.

CP of 200 eggs = ($\frac{200}{12}$) × 12 = ₹200. SP = (120 × 1.5) + (80 × 1) = 180 + 80 = ₹260. Profit = $\frac{60}{200}$ × 100 = 25%.

To find the selling price for a desired profit, we must first find the cost price using the loss information, then calculate the new selling price for the desired gain.

Step 1: Find the Cost Price (CP)

When selling at ₹5 per kg results in a 10% loss, we use:

Step 2: Calculate Selling Price for 15% Gain

For a 15% gain, the selling price should be:

Step 3: Simplify

Answer: ₹6.39 per kg (Option A)

SP = 2,000 × 0.8 × 0.9 × 0.95 = 2,000 × 0.684 = ₹1,368.

To find profit, we must track the cost price (including transportation) and selling price (after markup and discount).

Step 1: Calculate total cost price

The merchant buys goods for ₹6,000 and pays 10% extra for transportation:

Step 2: Calculate marked price

He marks up the goods by 25% on the cost price:

Step 3: Calculate selling price after discount

He offers a discount of 8% on the marked price:

Step 4: Calculate profit

Answer: The profit is ₹990 (Option A)

Let CP = 3x, MP = 5x. SP = 5x × 0.8 = 4x. Profit = 4x - 3x = x. Profit% = x/3x × 100 = 33.33%.

Let CP = 100. Current SP = 75 (25% loss). Desired SP = 125 (25% profit). Increase = 125 - 75 = 50. Percentage increase = $\frac{50}{75}$ × 100 = 66.67%.

MP = 500 × 1.80 = ₹900. SP = 900 × 0.75 = ₹675. Profit% = ($\frac{175}{500}$) × 100 = 35%

SP₁ = 1200 × 1.20 = ₹1,440. SP₂ = 1200 × 0.85 = ₹1,020. Total SP = ₹2,460. Total CP = ₹2,400. Profit% = ($\frac{60}{2400}$) × 100 = 2.5%

SP = 600 × 1.19 = ₹714. MP × 0.85 = 714. MP = $\frac{714}{0}$.85 = ₹840

Let CP = 100. Current SP = 88. Required SP = 108. % increase = (108-88)/88 × 100 = 22.73%

CP = ₹450. Profits = 10 + 30 + 50 = ₹90. Profit% = ($\frac{90}{450}$) × 100 = 20%... Recalc: (10+30+50)/450 = $\frac{90}{450}$ = 20%. Checking options: (100×1.1 + 150×1.2 + 200×1.25)/(450) = $\frac{605}{450}$ = 1.3444 = 34.44%... Error check: CP=450, SP=110+180+250=540, Profit=90, %=20%. Not in options as stated, actual is 20%

Let CP = 100. MP = 150. For 20% profit, SP = 120. Discount = 150 - 120 = 30. Discount% = ($\frac{30}{150}$) × 100 = 20%

CP₁ = ₹1,600, CP₂ = ₹800. SP₁ = 1600 × 1.20 = ₹1,920. SP₂ = 800 × 0.90 = ₹720. Total SP = ₹2,640. Profit = 2640 - 2400 = ₹240

SP₁ = 1200, Profit = 20%, so CP₁ = 1000. SP₂ = 1200, Loss = 20%, so CP₂ = 1500. Total CP = 2500. Total SP = 2400. Loss% = ($\frac{100}{2500}$) × 100 = 4%

If SP = 300 and loss = 25%, CP = $\frac{300}{0}$.75 = ₹400. For 25% profit, SP = 400 × 1.25 = ₹500

Total CP = 5000 + 500 = ₹5,500. MP = 5500 × 1.40 = ₹7,700. SP = 7700 × 0.80 = ₹6,160. Profit% = ($\frac{660}{5500}$) × 100 = 12%

MP × 0.85 × 0.90 = 459. MP × 0.765 = 459. MP = $\frac{459}{0}$.765 = ₹600

Profit = 9SP. If each SP = x, then Profit = 9x. Profit% = (9x)/(45x - 9x) × 100 = (9x)/(36x) × 100 = 25%

Let CP = x. SP = 1.15x. New CP = 0.9x. New SP = 1.15x - 4. New profit = 30%, so 1.15x - 4 = 1.3(0.9x). Solving: 1.15x - 4 = 1.17x gives x = 200
