Answer:

106

Explanation:

Each of the whole numbers could be 4 greater than the value it is rounded down to. Then the maximum original sum is ...

90 +4 +4 +4 +4 = 106

__

Example

The numbers could be 14, 24, 34, 34. Their rounded values are 10, 20, 30, 30, for a total of 90. The total of the original numbers is 106.
