I also think there is not a certain pattern or certain numbers fixed for particular question and when they will appear.
Oh ya! A quick tip for boldface questions:
On boldface questions you are asked to make out which function boldface parts serve in the argument (premise, conclusion, assumption) and\or what is the relationship between them.
Remember! To save time, eliminate answer choices that incorrectly define the first boldface type part. There is no need to continue reading them.
Also, I suppose you know what's given in the
MGMAT CR guide for boldface questions:
Figure out on boldface CR questions whether the part is "Conclusion" or "For the Conclusion" or "Against the conclusion".
