Imagine this series X,90,...,120,...,...,Y
Y-X=40
The largest possible amount for X is 89. So Y would be 129.
If the smallest number of three numbers is 120, the range would be 129-120=9
Just 0 can be the answer.
Option E

Let the numbers be
a,90,c,120,e,f,g in ascending order

g - a = 40
if a = 90, g = 130. Now range of largest three can be 130 - 120 = 10, when e =120
Range of largest three cannot be greater than 10.

E is correct.
