Q11 of 76 Page 2

Let A and B be two sets such that n(A) = 3 and n(B) = 2. If (x, 1), (y, 2), (z, 1) are in A × B, write A and B.

Here, A×B ={(x,1) ,(y,2) ,(z,1)} and n(A)=3 , n(B)=2


We know ,A×B = {(x,y) : xϵA and yϵ B}


∴ A={x,y,z} and B={1,2}

Let A = {1, 2, 3, 5}, B = {4, 6, 9} and R be a relation from A to B defined by R = {(x, y) : x − y is odd}. Write R in roster form.

Mark the correct alternative in the following:

If A = {1, 2, 4}, B = {2, 4, 5}, C = {2, 5}, then (A−B) × (B − C) is
