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) in R`

B

`(3, 8) in R`

C

`(6, 8) inR`

D

`(8, 7) in R`

Text Solution

Verified by Experts

The correct Answer is:
C
`because " " b gt 6`
`therefore " " (2, 4) notin R`
`" " (3, 8) notin R because 3 ne 8-2`
`" " (8, 7) notin R because 8 ne 7-2`
Therefore, `(6, 8) in R `
