(1) If Set A and Set B are combined, the resulting range exceeds 50. (2) The range of Set B is greater than the range of Set A.
I have one doubt regarding sets that sets contain only different set of numbers and lists are the ones in which same numbers can repeat. Can someone please clarify this doubt.

If A={0, 0, ..., 1} and B={0, 0, ..., 100} If set A and set B are combined, then range is 100-0=100 Again, If A={0, 0, ...., 30} and B={20, 20, ..., 60} then the combined set will {0,0,-----,20--,30,----60} Here Range =60-0=60 In both scenarios, combined set range is greater than 50. So, why statement A is insufficient? What I am missing? Bunuel

The question asks: is the range of Set B greater than 45?
If A={0, 0, ..., 1} and B={0, 0, ..., 100}, then he range of Set B IS greater than 45, it's 100 (the answer is YES); If A={0, 0, ...., 30} and B={20, 20, ..., 60}, then the range of Set B is NOT greater than 45, it's 40 (then the answer is NO).

Set A has 20numbers but since the numbers are not given we cannot decide what it's range is, same goes for set B. So from statement 1 the range is greater than 50 for both sets put together does not help us to determine if set B's range is greater than 45 Statement 2 says set B's range is greater than that of A Does not help Statement 1 and 2 put together does not give any new information. IMO E
