Answer:

108 kg

Explanation:

Mean mass = Total mass of students ÷ Total students

Initially,

60 kg = Total Mass ÷ 10 students

Total mass = 60 kg × 10

Total mass = 600 kg

After 2 students left,

48 kg = Total mass ÷ 8 students

Total mass = 48 kg × 8

Total mass = 384 kg

Mass of the 2 students = Difference in total mass

Mass of the 2 students = 600 kg - 384 kg

Mass of the 2 students = 216 kg

Mean mass = Total mass ÷ Total Students

Mean mass = 216 kg ÷ 2 students

Mean mass = 108 kg
