From this lesson I have learned that break even point and cost benefit analysis.
Break-even analysis is a method of studying the relationship among sales revenue, variable cost and fixed cost to determine the level of operation at which all the costs are equal to its sales revenue and it is the no profit no loss situation.
Here the equation ,
NPV= Present value of future benefits-Present value of future cost,
BCR= Present value of future benefits/Present value of future cost.
