Topic: Industrial Engineering

If the selling price is Rs. 300/unit, variable cost is Rs. 200/unit, and fixed cost is Rs. 50,000, what is the break-even quantity?

  • A. 100 units
  • B. 150 units
  • C. 200 units
  • D. 500 units

Answer: D. 500 units

Explanation: Break-even quantity is achieved when total revenue equals total costs.
Break-even Quantity = $\frac{\text{Fixed Cost}}{\text{Selling Price per unit} - \text{Variable Cost per unit}}$.
BEQ = $\frac{50000}{300 - 200} = \frac{50000}{100} = 500$ units.
