Answer 1

Answer:56

Step-by-step explanation:

Average=sum of age of 10 persons /total number

60=sum of age of 10 persons/10

sum of age of 10 persons=60x10=600

sum of age of 2 persons=sum of age of 10 persons-sum of age of 8 persons

=600-488=112

Average=sum of age of 2 persons/total number

=112/2=56
