I am getting it as B.
(I) we cannot do anything with the deviation. So, insufficient.
(II)40000 can be the worstcase mean. Then 100 * 40,000 > 100,000. Thus, the answer to the question is a definite NO.
Hence it is B.
Is the range of salary of 100 people smaller than 100,000?
1) The deviation of the salary of the 100 people is 20.
2) Each employee's salary is within 40000 of the average salary
Thnx & Rgds,
