SOLUTION
Cost of Revenue from Operations = Operating Cost-Operating Expenses
= 3,40,000 – 20,000
= Rs 3,20,000
Gross Profit = 3,20,000 × 2080
= Rs 80,000
Revenue from Operations = Cost of Revenue from Operations + Gross Profit
= 3,20,000 + 80,000
= Rs 4,00,000
Operating Profit = Revenue from Operations – Operating Cost
= 4,00,000 − 3,40,000
= Rs 60,000
Operating Profit Ratio = Operating Profit / Revenue from Operations × 100
= 60,000 / 4,00,000 × 100
= 15%
