Using LookupValue to retrieve max in separate tables - without using a calculated column

I have two columns containing data (in separate tables):

I have been able to retrieve the percentage value for the max percentage, but how do I go about doing the same for the actual amount of years based on the max percentage - using a measure and not a calculated column? Just to clarify, in this case I would like to have the text "0-3 years" in a measure.

I will be using the values in a dynamic text in a table so I will be using separate measures to try to achieve this.
