1) The median is greater than 25
2) 7 numbers are greater than 20 and less than 25


1. since median >25 and suppose if the 7 numbers are each 20, and all others are 25.01 including the median, then avg. isnot >25. in some other cases it could be >25.

2. suppose if the 7 numbers are all 20.1, and all others are 25.01 including the median, then avg. isnot >25. in some other cases it could be >25.

1 and 2 togather also not suff.........

It will be E even it's Integer in place of number.
