# Does "the diameter of each of them" mean that they have the same diameter?

The diameter of hole A is smaller than the diameter of each of holes B and C.

I would like to know whether the above sentence I created means that holes B and C have the same diameter.

• Sorry, misread your sentence. I meant that all we know is that the diameter of holes B and C are both larger than the diameter of A. We know nothing of their relationship to each other. By the way this kind of thing is used in tests of logical reasoning to catch students who are too quick to make assumptions. Commented Feb 23, 2018 at 16:08
• I was worried that "the diameter of each of holes B and C" means only they have the same diameter and that "the diameters of holes B and C" mean only they have different diameters. According to your comments, each of these expressions can be interpreted as having both meanings. Commented Feb 23, 2018 at 17:08
