20, 30 are in int format not in long int hence 2nd method is call.

float GetNumber (int Number) takes an integer arguments and its return type is float.

Typecasting will not done in argument. So int will treated as int and long int as long int.

I think the answer will be 19, 29. Reason in case of overloading match to call is from top to bottom. In the above question long int is higher data type thus, can accept int for both the calls.
