Answer 3

uses crt;

var toan,ly,hoa,van:byte; tb:real; ten:string;

Begin

clrscr;

write('Tinh dtb va Xep hang');

writeln('Nhap ten hs: ');

readln(ten);

write('Nhap diem Toan Ly Hoa Van: ');

readln(toan,ly,hoa,van);

tb:=(toan+ly+hoa+van)/4 (mấy môn này bình đẳng)

write(ten,tb:3:1,' ');

if tb>=8.0 then write('Hluc: Gioi');

else if tb>=6.5 then write('Hluc: Kha');

else if tb>=5.0 then write('Hluc: Tb');

else write('Hluc: Yeu');

readln

End.
