A trader borrows 5000 from a financial institution at 4% rate of interest per annum. He repays 1000 at the end of each year. How much does he still have to pay after the third year?

Answer 1

At the end of the first year, the trader still has to pay 5000 - 1000 = <<5000-1000=4000>>4000 dollars
At the end of the second year, the trader still has to pay 4000 - 1000 = <<4000-1000=3000>>3000 dollars.
At the end of the third year, the trader still has to pay 3000 - 1000 = <<3000-1000=2000>>2000 dollars. Answer: \boxed{2000}.
