80. Three students' scores in a math exam are all different, and none of them scored 0 or 100. Each student knows their own score and ranking, but not the scores or rankings of the other two. They then provide information to each other:
甲 says: “My score is a multiple of 10.”
乙 says: “My score is a multiple of 12.”
丙 says: “My score is a multiple of 14.”
After thinking, 乙 says: “Now I know your scores.”
So, 乙's score is $\qquad$ points.
Answer: 84
