Quantitative Aptitude - MCQ Practice Questions

SP = CP × (1 + profit%) = 800 × 1.35 = 1080.

To find the new workforce after an 18% increase, we calculate the increase amount and add it to the original number of employees.

Step 1: Identify the increase percentage

The company increased its workforce by 18%, meaning we need to find what 18% of 500 employees represents.

Step 2: Calculate the number of new employees added

Step 3: Find the total workforce in 2025

Add the increase to the original number of employees:

Alternatively (using multiplier method):

A 18% increase means the new total is $100\%+18\%=118\%$ of the original:

Answer: The company now has 590 employees (Option A)

SI = (P × R × T)/100 = (5000 × 8 × 3)/100 = 1200. Total = 5000 + 1200 = 6200.

Value after 2024 = 10 × 1.12 = 11.2 lakhs. Value after 2025 = 11.2 × 1.08 = 12.096 ≈ 12.09 lakhs.

Equivalent discount = 100 - (90 × 80)/100 = 100 - 72 = 28%.

MP = 8000 × 1.60 = 12,800. SP = 12,800 × 0.75 = 9,600. Profit = 9,600 - 8,000 = 1,600. Profit% = (1,$\frac{600}{8}$,000) × 100 = 20%.

Let CP = 100. MP = 140. SP = 140 × 0.75 = 105. Profit = 5%.

New salary = 50,000 × 1.12 = 56,000.

30% of x = 90, so x = 300. 50% of 300 = 150.

After 15% increase: 1000 × 1.15 = 1150. After 10% decrease: 1150 × 0.9 = 1035.

80% of original = 800. Original = $\frac{800}{0}$.8 = 1000.

Profit = 750 - 600 = 150. Profit% = ($\frac{150}{600}$) × 100 = 25%.

Increase = 100. Percentage = ($\frac{100}{400}$) × 100 = 25%.

Marks = 150 × 0.72 = 108.

CP = 100, MP = 160, SP = 160 × 0.8 = 128. Profit% = 28%.

After 15% discount: 2000 × 0.85 = 1700. After 10% discount: 1700 × 0.9 = 1530.

When a man sells an item at a loss, the selling price is calculated as a percentage reduction from the cost price. Here, we lose 15% of the original value.

Step 1: Identify the given information

Cost Price (C.P.) = ₹1200

Loss percentage = 15%

Step 2: Calculate the loss amount

Loss amount is 15% of the cost price:

Step 3: Calculate the selling price

Selling price is obtained by subtracting the loss from the cost price:

Alternative method (direct formula):

When there is a loss of 15%, the selling price is 85% of the cost price:

Answer: The selling price is ₹1020 (Option D)

Value = 10,000 × (1.08)² = 10,000 × 1.1664 = 11,664.

Sale price = 500 × 0.7 = 350.

CP × 1.1 = 1100, so CP = 1000.
