\(P = {1, 3, 5, 7, 9}, Q = {2, 4, 6, 8, 10, 12}, R = {2, 3, ...

P=1,3,5,7,9,Q=2,4,6,8,10,12,R=2,3,5,7,11 are subsets of U=1,2,3,...,12. Which of the following statements is true?

A.

QR=

B.

RP

C.

(RP)(RU)

D.

n(PR)=2

Correct answer is C

All the statements are false except option C.

RP=3,5,7andRU=2,3,5,7,11 

\therefore (R \cap P) \subset (R \cap U)
