Q. 16 Let R be the relation in the set N given by $R = \{(a, b) : a = b - 2, b > 6\}$. Choose

(A) $(2, 4) \in R$
(B) $(3,8) \in R$
(C) $(6,8) \in R$
(D) $(8,7) \in R$

$R = \{(a, b) : a = b - 2, b > 6\}$

(A) Since, $b< 6$ so $(2, 4) \notin R$

(B) Since, $3\neq 8-2$  so  $(3,8) \notin R$

(C) Since, $8> 6$  and  $6=8-2$  so  $(6,8) \in R$

(d) Since,$8\neq 7-2$ so  $(8,7) \notin R$

The correct answer is option C
