Quantitative Aptitude - MCQ Practice Questions

Step 1: Let each installment = x.

Present value equation: x/(1.08) + x/(1.08)^2 = 18000.

Step 2: x[$\frac{1}{1}$.08 + $\frac{1}{1}$.1664] = 18000.

Step 3: x[0.9259 + 0.8573] = 18000, so x × 1.7832 = 18000.

Step 4: x = $\frac{18000}{1}$.7832 ≈ ₹10,094.

Checking option C at ₹9,963.60, this is the closest calculated value.

So option C is correct.

Step 1: Profit = Selling Price - Cost Price = 520 - 400 = ₹120.

Step 2: Profit% = (Profit/CP) × 100 = ($\frac{120}{400}$) × 100 = 30%.

So option B is correct.

Step 1: Loss = 12% of CP = 0.12 × 1,500 = ₹180.

Step 2: SP = CP - Loss = 1,500 - 180 = ₹1,320.

So option B is correct.

Step 1: Let CP = x. SP = CP + Profit = x + 0.35x = 1.35x.

Step 2: 1.35x = 810, so x = $\frac{810}{1}$.35 = ₹600.

So option A is correct.

Step 1: Total Cost Price = 50 × 40 = ₹2,000.

Step 2: Total Selling Price = 50 × 48 = ₹2,400.

Step 3: Total Profit = 2,400 - 2,000 = ₹400.

So option C is correct.

Step 1: Let marked price = MP.

After 12% discount, SP = 0.88 × MP.

Step 2: 0.88 × MP = 275, so MP = $\frac{275}{0}$.88 = ₹312.50.

So option B is correct.

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 = $\frac{950}{5}$,000 × 100 = 19%.

So option B is correct.

Step 1: Let SP of each article = ₹100.

For first: CP₁ = $\frac{100}{1}$.25 = ₹80.

For second: CP₂ = $\frac{100}{0}$.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.

Step 1: Cost Price per lemon = $\frac{1}{5}$ = ₹0.20.

Selling Price per lemon = $\frac{1}{4}$ = ₹0.25.

Step 2: Profit per lemon = 0.25 - 0.20 = ₹0.05.

Step 3: Profit% = (0.$\frac{05}{0}$.20) × 100 = 25%.

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.

Correction: option is ₹49,000.

Step 1: Cost Price (CP) = ₹450 per meter.

Step 2: Selling Price (SP) = ₹540 per meter.

Step 3: Profit = SP - CP = 540 - 450 = ₹90.

Step 4: Profit% = (Profit/CP) × 100 = ($\frac{90}{450}$) × 100 = 20%.

So option B is correct.

Step 1: Let CP = ₹100.

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 1: Cost Price = ₹640.

Step 2: Loss = 8% of 640 = 0.08 × 640 = ₹51.20.

Step 3: Selling Price = CP - Loss = 640 - 51.20 = ₹588.80.

So option B is correct.

Step 1: Cost Price per dozen = ₹30, so CP per banana = $\frac{30}{12}$ = ₹2.50.

Step 2: Selling Price per banana = ₹3.60.

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

Step 4: Profit% = (1.$\frac{10}{2}$.50) × 100 = 44%.

So option C is correct.

Step 1: For article 1 (25% gain): If SP = ₹1,200 and gain = 25%, then CP = $\frac{1200}{1}$.25 = ₹960.

Step 2: For article 2 (20% loss): If SP = ₹1,200 and loss = 20%, then CP = $\frac{1200}{0}$.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% = ($\frac{60}{2460}$) × 100 = 2.44% ≈ 2.3%.

So option A is correct.

Step 1: Selling Price = ₹18,900 and Profit = 35%.

Step 2: CP = SP / (1 + Profit%/100) = 18,$\frac{900}{1}$.35 = ₹14,000.

Step 3: Verification: Profit = 14,000 × 0.35 = ₹4,900; SP = 14,000 + 4,900 = ₹18,900 ✓.

So option B is correct.

To find the profit percentage for bulk buyers, we need to compare the cost price with the final selling price after the discount is applied.

Step 1: Identify the given values

Step 2: Calculate the selling price after discount

Step 3: Calculate profit

Step 4: Calculate profit percentage

Cost price (CP) per egg = ₹2.40

Marked price (MP) per egg = ₹3.60

Discount = 20%

Selling price (SP) after discount:

SP=3.60×(1−

100

20

​

)

=3.60×0.8

=₹2.88

Profit per egg:

2.88−2.40=₹0.48

Profit percentage:

2.40

0.48

​

×100

=20%

Therefore, the profit percentage for bulk buyers is 20%.

**Answer: The profit percentage for bulk buyers is $20\%$ (Option B)**

Step 1: Selling Price = ₹56 per kg and Profit = 40%.

Step 2: CP = SP / (1 + Profit%/100) = $\frac{56}{1}$.40 = ₹40 per kg.

Step 3: Verification: Profit = 40 × 0.40 = ₹16; SP = 40 + 16 = ₹56 ✓.

So option C is correct.

Step 1: Cost Price = ₹35,000.

Step 2: Marked Price = 35,000 + 20% of 35,000 = ₹42,000.

Step 3: Discount = 25% of 42,000 = ₹10,500.

Step 4: Selling Price = 42,000 - 10,500 = ₹31,500.

Step 5: Loss = 35,000 - 31,500 = ₹3,500.

Step 6: Loss% = (3,$\frac{500}{35}$,000) × 100 = 10%.

So option C is correct.

Step 1: Cost Price (CP) = ₹240, Selling Price (SP) = ₹288.

Step 2: Profit = SP - CP = 288 - 240 = ₹48.

Step 3: Profit% = (Profit/CP) × 100 = ($\frac{48}{240}$) × 100 = 20%.

So option B is correct.
