Q1 .

 An automobile company manufactures both a two wheeler (TW) and a four wheeler (FW). A company manager wants to make the production of both types of vehicle according to the given data below:

1st data, 
Total number of vehicle (two-wheeler + four-wheeler)=v

2nd data, 
Total number of wheels = W

The task is to find how many two-wheelers as well as four-wheelers need to manufacture as per the given data.

Example :

Input :
200  -> Value of V
540   -> Value of W

Output :
TW =130 FW=70

Explanation:
130+70 = 200 vehicles
(70*4)+(130*2)= 540 wheels

Constraints :

2<=W
W%2=0
V<W
Print “INVALID INPUT” , if inputs did not meet the constraints.

The input format for testing 
The candidate has to write the code to accept two positive numbers separated by a new line.

First Input line – Accept value of V.
Second Input line- Accept value for W.
The output format for testing 

Written program code should generate two outputs, each separated by a single space character(see the example)
Additional messages in the output will result in the failure of test case*/

Code : 

import java.util.Scanner;
public class Problem1{
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);

        int v=sc.nextInt();
        int w=sc.nextInt(); 

        int result= ((v*4)-w)/2;

        System.out.println("TW : "+result+" FW : "+ (v-result));


    }
}
