A multi-product company furnishes the following data relating to the year 2009:

I half of the Year Rs.

II half of the Year Rs.

Sales

1,35,000

1,50,000

Total cost

1,20,000

1,29,000

Assuming that there is no change in the prices and variable costs and that the fixed expenses are incurred equally in the two half-year periods, you are required to calculate for the year 2009, the following:

  1. the profit–volume ratio.
  2. the fixed expenses.
  3. the break-even sales.
  4. the percentage of margin of safety to total sales.
