Example:

Calculate Rate of Investment from the following data:

Sales = Rs. 1,80,000

Profit = Rs. 18,000

ADVERTISEMENTS:

Investment or capital employed = Rs 90,000

Solution:

Return on Investment or capital employed:

18,000/90,000 x 100 = 20%

ADVERTISEMENTS:

Capital turnover = 1,80,000/90,000 = 2times

Net profit ratio = 18000/1,80,000 x 100 = 10%

Return on capital employed = 2 x 10% = 20%
