Answer:

Greatest no of 3 digit divisible by 10=990

Smallest no of 3 digit divisible by 10=100

=series will =110,120.....990

=common difference =10

=greatest divisible no=smallest divisible no+(x-1) common difference

=990=100+(x-1)10

=990-100=(x-1)10

=890=(x-1)10

=890/10=x-1

=x-1=89

=X=89+1

=X=90
