Calculate the net profit from the following information-

₹420000

Net profit = operating profit - non-operating expenses + non-operating income
               = 400000 - 30000 + 50000
               = ₹420000

* Operating profit= Sales X operating profit ratio
                       = 2000000 X 20/100
                       = ₹400000

*Operating Profit Ratio = 100 – Operating Ratio
                               = 100 - 80
                                = 20%
