Final answer:
The security alarm manufacturer needs to sell 100,000 units to cover the fixed costs, calculated using the break-even point formula which is Fixed Costs divided by the difference between Selling Price and Variable Cost per unit.
Step-by-step explanation:
To determine how many security alarm devices need to be sold to cover the fixed costs, one must calculate the break-even point.
The formula for the break-even point in units is given by:
Break-even point (units) = Fixed Costs / (Selling Price - Variable Cost per unit)
Using the given values:
- Fixed Costs = Rs. 180,000,000
- Selling Price = Rs. 4,500
- Variable Cost per unit = Rs. 2,700
Therefore:
Break-even point (units) = 180,000,000 / (4,500 - 2,700)
Break-even point (units) = 180,000,000 / 1,800
Break-even point (units) = 100,000 units
The manufacturer needs to sell 100,000 security alarm devices to cover their fixed costs of Rs. 180,000,000.
