Must be E.

1) Range = 5. INSUFF to find MEAN.
2) Median = 5. INSUFF to find MEAN.

(1) & (2),

Still insuff -> (2,5,7) (3,5,8)...... several egs that satisfy the condition.

E

St1: Clearly INSUFF

St2: Clearly INSUFF

Combined:

Numbers are x,5,y

The list could be x could be 0 to 5 and y could be from 5 to 10. So INSUFF

I, II ...can't find mean using either of these.

I + II -> Gives the list of numbers as X 5 Y, where x,y could be (1,6), (2,7), (3,8)...INSUFF.

Hence, E.
