Step-by-step explanation:

(Sum of 15 students)/15 = 60 kg

Sum of 15 students = 60 × 15 kg

= 900 kg

5 students left the class

(Sum of 5 students)/5 = 40 kg

Sum of 5 students = 40 × 5 kg

= 200 kg

Sum of the 10 students who left in the class =

= Sum of 15 students - Sum of 5 students

= 900 kg - 200 kg

= 700 kg

Avg of the 10 students is = 700/10

= 70 kg

hence, the answer is 70 kg
