Write an algorithm to calculate Simple Interest

Write an algorithm to calculate Simple Interest :-

Step 1 : START 

Step 2 : Declare variables  p , n , r  and  si .

Step 3 : Read the values of variable  p ( principal ) , n ( Number of years ) , r ( Rate of Interest ) .

Step 4 : calculate the values of  “ si = ( p * n * r )/100 “ .

Step 5 : Display si ( simple interest ) .

Step 6 : STOP
