onBackPressed for two seperate pages from one page in Android

Question

I'm kind of new to Android. I'm implementing a small android application. It has 3 pages.

Page A

Page B

Page C

There are buttons in Page A and Page B which can go to Page C. What I need to know is, when I goto Page C by clicking on Page A button I need to go back to Page A using onBackPressed() and when I goto Page C by clicking on Page B button I need to go back to Page B using onBackPressed()

Here is the code I used.

@Override
    public void onBackPressed()
    {
        super.onBackPressed();
        startActivity(new Intent(C.this, A.class));
        finish();

    }

As far as I know I can't call two onBackPressed() in the same class.

So, what should I do?

Start Activity C from A/B

 btnFromC.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(), C.class);
                finish();
                startActivity(intent);
            }
        });

Try this, is not the Best answer but it works:

Activity A:

btnFromC.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(), C.class);
                intent.putExtra("comeFrom", 0);
                startActivity(intent);
            }
        });

Activity B:

btnFromC.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(), C.class);
                intent.putExtra("comeFrom", 1);
                startActivity(intent);
            }
        });

Activity C:

 int comeFrom;
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
         Intent intent = this.getIntent();
         comeFrom = intent.getIntExtra("comeFrom", 0);
}

@Override
    public void onBackPressed()
    {
        super.onBackPressed();
  Intent intent = null;

       switch(comeFrom){
      case 0:
        intent = new Intent(getApplicationContext(), A.class);
        break;
      case 1:
        intent = new Intent(getApplicationContext(), B.class);
        break;
       }
       startActivity(intent);

    }
