// CPP Program to Compute Simple Interest

#include <iostream>

using namespace std;

int main()
{
	int n, d;
	float r = 15,ans;

	cout << "Enter Amount :--> ";
	cin >> n;

	cout << "Enter Interest Rate :--> ";
	cin >> r;

	cout << "Enter Duration (in months) :--> ";
	cin >> d;

	ans = (n * r * d) / 100;

	cout << "\nSimple Interest :--> " << ans;

	return 0;
}

Output:

Enter Amount :--> 1000
Enter Interest Rate :--> 1.5
Enter Duration (in months) :--> 12

Simple Interest :--> 180.00
