Exercise 1.1 Problem 16 Solution
16. Let R be the relation in the set N given by R = {(a, b) : a = b – 2, b \gt 6}. Choose the correct answer.
(A) (2, 4) ∈ R (B) (3, 8) ∈ R (C) (6, 8) ∈ R (D) (8, 7) ∈ R
(A) (2, 4) ∈ R (B) (3, 8) ∈ R (C) (6, 8) ∈ R (D) (8, 7) ∈ R
Given that R is the relation in the set N given by R = {(a, b) : a = b~–~2, b \gt 6}
Check for option A:
2 = 4 – 2 but {4 \ngtr 6}. So, A is not correct option.
Check for option B:
3 ≠ 8 – 2. So, B is not correct option.
Check for option C:
6 = 8 – 2 and 8 > 6. So, C is correct option.
Check for option D:
8 ≠ 7 – 2. So, D is not correct option (as we already know that C is correct option, we don’t have to check for D)
