SOLUTION
Net Sales = Rs. 8,20,000
Gross Profit = Net Sales – Cost of Goods Sold
= 8,20,000 – 5,20,000
= Rs. 3,00,000
Net Profit = Gross Profit – Operating Expenses – Interest on Debentures + Profit on Sale of Fixed Asset
= 3,00,000 – 2,09,000 – 40,500 + 81,000
= Rs. 1,31,500
Net Profit Ratio = Net Profit / Net Sales × 100
= 1,31,500 / 8,20,000 × 100
= 16.04%
