Answer 2

Answer :

Required C++ Program :

To Find Simple Interest ;

#include <iostream>

using namespace std;

int main ( )

{

float p_Amount , n_Year , i_Rate ,

int_Amount ;

cout <<"Enter the Principal Amt. in

Rupees: " ;

cin>> p_Amount ;

cout<<"Enter the no.of Years of

Deposit : " ;

cin>>n_Year ;

Cout<<"Enter the rate of interest in

Percentage : " ;

cin>> i_Rate ;

int_Amount = p_Amount * n_Year *

i_Rate / 100 ;

cout <<"Simple Interest for the

Principal Amt. "

<<p_Amount

<<"Rupees for a period

of"<<n_Year

<<"Years at the rate of

Interest"<<i_Rate

<<"is " <<int_Amount <<"

Rupees" ;

return 0;

}

Output :

•Enter the Principal Amt in Rupees : 100

•Enter the no.of years of Deposit : 2

•Enter the rate of interest in Percentage: 10

•Simple Interest for the Principal Amt 100 Rupees for a period of 2 Years at the rate of interest 10 is 20 Rupees.
