650 to 700 or 700 to 750
for rounding we take two groups into consideration
the groups are of 50 numbers each
this group can between any two hundred's
in the above example,
the number is rounded to 700 which means the original number is in either of the two groups
the number is either in the group of 50 numbers before 700 or after 700
hence it can fall in either of the two intervals given below
650 to 700 or 700 to 750
