Annual capacity of a plant producing phenol is $100$ metric tons. Phenol sells at INR $200$ per kg, and its production cost is INR $50$ per kg. The sum of annual fixed charges, overhead costs and general expenses is INR $30,00,000$. Taxes are payable at $18 \%$ on gross profit. Assuming the plant runs at full capacity and that all the phenol produced is sold, the annual net profit of the plant (in INR) is
- $1,39,40,000$
- $1,50,00,000$
- $98,40,000$
- $1,20,00,000$
