To maximize the number of points scored by the team that finishes 5th, we need to minimize the points scored by the last 3 teams.
Matches played by the last 3 teams =3C2×3=9
Points scored by the last 3 teams =9×4=36
Total points of the tournament = 336
Remaining points = 336-36 = 300
Maximum points scored by the team =3005=60 points
