SOLUTION
Net Profit = Operating Profit + Non-Operating Incomes – Non Operating Expenses
= 40,000 + 22,000 – 2,000
= Rs. 60,000
Operating Profit Ratio = 100 − Operating Ratio
=100 – 90
=10%
Operating Profit = 4,00,000 × 10%
= Rs. 40,000
Net Profit Ratio = Net Profit / Revenue from operations × 100
= 60,000 / 4,00,000 × 100
= 15%
