PGDBA 2022 Question Paper | Quant

CAT 2022 Quant was dominated by Arithmetic followed by Algebra. In Arithmetic, the questions were dominated by topics like Speed-time-distance, Mixture and Alligations. This year, there was a surprise. The questions from Geometry were relatively on the lower side as compared to the previous years. There were 8 TITA Qs this year. Overall this section was at a medium level of difficulty.

Question 7 : Let \(P, Q, R\) be any three sets. Consider the following two statements:
(I) \(\quad P-(Q-R)=(P-Q) \cup R\)
(II) \(\quad P-(Q \cup R)=(P-Q)-R\)
Which of the following is TRUE?
