Solve if/else problems in getting Scanner input

I created two Scanner objects ant got them. but when getting inputs is finished, if/else codes do not work. where is the problem? can you explain me please and write the right code?tnx.

import java.util.Scanner;

public class NestedIf {

public static void main(String[] args) {


    Scanner iqInput=new Scanner(System.in);
    System.out.println("Please enter your IQ: ");
    iqInput.nextDouble();


    Scanner termMeanInput=new Scanner(System.in);
    System.out.println("Please enter your term mean: ");
    termMeanInput.nextDouble();


    if(iqInput.hasNextDouble() && termMeanInput.hasNextDouble()){

        if(iqInput.nextDouble()>110 && termMeanInput.nextDouble()>18){
            System.out.println("You got 30 percent discount.");

        }else if(iqInput.nextDouble()>100 && termMeanInput.nextDouble()>17){
            System.out.println("You got 20 percent discount.");

        }else if(iqInput.nextDouble()<100 && termMeanInput.nextDouble()<17){
            System.out.println("You have no discount");
        }
    }else{
        System.out.println("Please enter the right format");
    }
}

}
