1. Yes

2. No

Step-by-step explanation:

You can have a case such as 26,30,30,30,30 and another case : of 4,40,40,32,8 satisfying the 2 statements at the same time but in the 2nd case, the average that is less than 28.

From the given statements combined together, to get e-a=4. So once you get this information, you can have a big range of values that may or may not have average >28.
