  1. those who like maths and science will follow engineering for advance level.
  2. those who likes history or music will follow art for advance level.

Is this correct for final two?

No. It could be:

will_follow(Student, engineering) :-
    likes(Student, maths),
    likes(Student, science).

will_follow(Student, art) :-
    likes(Student, history)  ;
    likes(Student, music).

1) Does saman like maths or music?

likes(saman, art) ; likes(saman, music).     % intentionally incorrect

2) Who likes science and music?

likes( Who, science) , likes( Who, maths).   % intentionally incorrect

3) who will do engineering?

will_follow( Who, arts ).                    % intentionally incorrect

Since this looks like an assignment, I've intentionally used wrong names here and there. You will have to correct those.
