There are 9 ways for him to hold AQ, and 12 ways to hold AA or QQ, so the correct percentages should be:

AQ: 43%
AA or QQ: 57%

And you also have to consider the likelihood that he plays a big pair that way preflop (and a set on the flop) versus AQ and two pair. That's a pretty poorly played AA or QQ, IMO, so I would shade the percentages a bit further in favor of AQ, maybe call it 55% AQ/45 or 50/50.

There's also the possibility of KcJc, KcTc, QcTc that might play the hand this way.

Easy call, IMO.
