## Program to find the simple interest

### Explanation

Simple Interest is the convenient method used in banking and economic sectors to calculate the interest charges on loans.It gets estimated day to day with the help of some mathematical terms.

### Formula

```Simple Interest = (P × R × T)/100
where P = Principal Amount, R = Rate per Annum, T = Time (years)
```

### Algorithm

1. Define Principal, Interest and Time of loans.
2. Apply in the formula.
3. Print the Simple Interest.

O(1)

### Python

```P= 5000 #Principal Amount
R=15 #Rate
T=1 #Time
SI  = (P*R*T)/100; # Simple Interest calculation
print("Simple Interest is :");
print(SI);  #prints Simple Interest
```

Output:

``` Simple Interest is:  750.0
```

### C

```#include<stdio.h>
int main()
{
float P , R , T , SI ;
P =34000; R =30;  T = 5;
SI  = (P*R*T)/100;
printf("\n\n Simple Interest is : %f", SI);
return (0);
}
```

Output:

```Simple Interest is:  51000.000
```

### JAVA

```public class Main
{
public static void main (String args[])
{	float p, r,  t,  si; // principal amount, rate, time and simple interest respectively
p = 13000;  r = 12; t = 2;
si  = (p*r*t)/100;
System.out.println("Simple Interest is: " +si);
}}
```

Output:

```Simple Interest is:  3120.0
```

### C#

```using System;
class main
{   static void Main()
{ int P;
double R, T,  SI;
P = 12000;
R = 5;
T =0.5;
SI  = (P*R*T)/100;
Console.WriteLine("Simple Interest is: "+SI);
}}
```

Output:

```Simple Interest is:  300.00
```

### PHP

```<?php
\$p = 2000;
\$r = 10;
\$t = 1;
\$si =   (\$p*\$r*\$t)/(100);
echo("Simple Interest is: ");
echo(\$si);
?>
```

Output:

```Simple Interest is: 200
```
