ExplanationThe range of 200 measurements = 17 cms

If 49.5 is the lowest measurement in the set

The highest measurement in the set of measurement = 49.5 + range = 49.5 + 17 = 66.5 cms

If 49.5 is the highest measurement in the set

The lowest measurement in the set of measurement = 49.5 - range = 49.5 - 17 = 32.5 cms.

In the second case we have two values that lie between 32.5 cms and 49.5 cms.

Thus option is C and D is correct.
