To raise money for a new business a man asks you to loan him
     To raise money for a new business a man asks you to loan him some money. He offers to pay you $3000 at the end of four years. How much should you give him now if you want 12% interest per year on your money?  $1800.15  $1906.50  $2101.50  $1721.18 
  
  Solution
We would apply compound interest formula:
Amount after 4 yrs = Principal( 1+ r/100)^n
where n is no. of years ; r= rate of interest
3000 = P[ 1+ 0.12]^4
3000 = P*1.5735
Principal he needs to give = 3000/1.57 = $ 1906.55
