Or you can just use 

select from, to, id 
from table1 
where id like'%0' and from ='A' and to = 'B'

select * from 
(select * from table where from = 'A' and to ='B' order by ID)
where mod(rownum/10,1) = 0

It first takes only those from 'A' to 'B', then giving them rownums, and selecting only those in the 10th 20th ETC places..
