Statement 1: Sufficient
The range will not change if the set has only positive numbers.
Ex: S = {1,2,3,4 }
Here Range is 3. Adding this number to the set will not change it.
Statement 2: Insufficient
T = {-1, 0, 1, 2, 3, 4}
Here range is 5. Adding this to the set will change the range to 6.
Mean of this new set is 15/6 which is less than the range (6)
Hence the Answer should be A
