A company sells 2,75,000 units of its product at Rs. 47.50 per unit. Variable costs are Rs. 27.50 per unit (manufacturing costs of Rs. 10 and selling cost Rs. 2.50 per unit). Fixed costs are incurred uniformly throughout the year and amount to Rs. 40,00,000 (including depreciation of Rs. 10,00,000). There is no beginning or ending inventories.
