Explanation

Of the 20 oldest employees, 18 are in the 55–64 age-group, and 2 are in the 45–54 age-group. Therefore the youngest of the 20 employees is in the 45-54 age-group, and the oldest is in the 55- 64 age-group. The youngest of the 20 employees could be 45 years old and the oldest could be 64 years old. In this case, the range of their ages would be 64 – 45, or 19 years.

On the other hand, the youngest could be 54 years old and the oldest could be 55 years old, so the range of their ages would be 1 year. Because there are cases where the range is greater than 11 years and cases where it is less than 11 years, the correct answer is Choice D.

Its not necessary that there must be a member with upper limit in the frequency basket.

It can be but not a must.

This is a very confusing question. What is the name for these type of problems? Is there an easier way to tackle these?
