An English Training Center opens a new business branch in the property sector and is interested opened a boarding house in the East Coast area.

This project requires an investment of an initial amount of 5 billion to buy ready-made properties, with 25 boarding rooms.

visible occupancy rate (rented room rate) is 80% and rental income is 3 million per month.

If the cost of electricity and water is 20 million per year, then calculate: - Earnings before tax per year - Profit after tax per year, tax rate = 20% - Payback period (how many years payback)

When it runs after 10 years, the property sells for 3 billion, and interest at this time is 12%, then determine: - Net value now - Internal Rate of Return - Profitability index
