How to calculate the discounted price.

Example.1:-Find the simple interest if $2000 is invested for 2 years on 25% P.A.

solve:-simple interest(SI) = P x R x T / 100 = 2000*25*2/100 = 1000

Total Amount = SI + Principal Amount = 1000 + 2000 = 3000

Example.2:-Find the simple interest if $1000 is invested for 2 years and 6 months on 10% pa.

solve:-T = 2 + 6/12 = 2 + 1/2 = 5/2 yr

SI = P x R x T / 100 = 1000*10*2.5/100 = $250

Total Amount = $250 + $1000 = $1250
