0 Binomial Theorem PYQ (Solutions)

Binomial Theorem (expansions, coefficients) is a less common topic in CAT. It falls under higher algebra (“modern math”).

• In the 2017–2024 period, pure binomial expansion questions were rare.
• CAT papers focused more on core arithmetic/algebra, and if binomial appeared, it was typically one of the “Miscellaneous” math questions.
  • For instance, CAT 2017 had 2 miscellaneous questions across the paper which could include a binomial concept.
• Generally, 0–1 question on Binomial Theorem might appear in a given year. Many years saw none at all.

It’s not a regularly tested topic in recent CATs. It is advisable to know the basics, but past official data shows binomial expansions have not been a significant contributor to CAT question sets from 2017–2024.
