3. A new factory is to be established to produce reinforcement bars for the construction industry. This will require an initial investment of Birr 10 million. It is expected that after three years of operation an additional investment of Birr 5 million will be required; and after six years of operation, another investment of Bill 3 million. Annual operating costs will be Birr 3 million and annual revenues will be Birr 8 million. The life of the plant is 10 years. If the interest rate is 15% per year, compounded annually, a. what is the NPV of this plant?

b. Is it a worthy investment? Why?

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
