1.	Let R be a relation in the set N given by R={(a,b): a+b=5, b>1}. Which of the following will satisfy the given relation?(a) (2,3) ∈ R(b) (4,2) ∈ R(c) (2,1) ∈ R(d) (5,0) ∈ RThis question was addressed to me during an interview.My enquiry is from Types of Relations topic in division Relations and Functions of Mathematics – Class 12
Answer» Right OPTION is (a) (2,3) ∈ R Explanation: (2,3) ∈ R as 2+3 = 5, 3>1, thus satisfying the given CONDITION. (4,2) doesn’t BELONG to R as 4+2 ≠ 5. (2,1) doesn’t belong to R as 2+1 ≠ 5. (5,0) doesn’tbelong to R as 0⊁1
