A) 1
B) 2
C) 4
D) 8
Correct Answer: B
Solution :
[b]Given that \[F(n)=\]set of all divisors of n except 1 \[\therefore F(20)=\{2,4,5,10,20\}\] And \[F(16)=\{2,4,8,6\}\] \[\therefore F(20)\cap F(16)=\{2,4,5,10,20\}\cap \{2,4,8\}=\{2,4\}\]Also, \[\{F(20)\cap F(16)\}\subseteq F(y)\] So, least value of y = 2You need to login to perform this action.
