Given three integers P,R and T, denoting Principal, Rate of Interest and Time period respectively.Compute the simple Interest.
Example 1:
Input:
P=100
R=20
T=2
Output:
40.00
Explanation:
The simple interest on 100 at a rate
of 20% across 2 time periods is 40.
Example 2:
Input:
P=999
R=9
T=9
Output:
809.19
Explanation:
The simple interest on 999 at a rate
of 9% across 9 time periods is 809.19
Your Task:
You don't need to read input or print anything.Your Task is to complete the function simpleInterest() which takes three integers P,R and T and returns the simple interest.
Expected Time Complexity:O(1)
Expected Auxillary Space:O(1)

Constraints:
1<=P<=10^{5}
1<=R,T<=100
