Answer to above Question is E. (Cannot be determined). In order to justify, I have quoted an example below:
Let us consider the following sets - Set I : {1,4,6,9,20}, Set II : {3,6,8}, and Set III : {29,32,34}
The ranges of Set I, Set II and Set III are 19, 5 and 5 respectively.
If Set I and Set II are combined, The Range of resulting Set will be remain same i.e, 19.
However, If Set I and Set III are combined, The Range of resulting Set will be 33.
So I want to clarify that, addition of different sets with same range resulted in different ranges for the combined sets.
