Question

Let A= 1,2,3,5 and B= 4,6,9 and a relation R from A to B is defined by R= (x, y): the difference between x and y is odd; x ∈ A and y ∈ B . Then Roster form of R is ...K.... Here, K refers to (A)  (1,4),(1,6),(1,9)  (B)  (1,4),(1,6),(2,9),(3,4),(3,6),(5,9)  (C)  (1,4),(1,6),(2,9),(3,4),(3,6),(5,4),(5,6)  (D) None of the above

Difference between x and y is odd, if one of them is odd. ∴ In Roster form R= (1,4),(1,6),(2,9),(3,4),(3,6),(5,4),(5,6)

Q. Let $A = {1, 2, 3, 5}$ and $B = {4, 6, 9}$ and a relation $R$ from $A$ to $B$ is defined by $R = {(x, y)$ : the difference between $x$ and $y$ is odd; $x \in A$ and $y \in B}$ . Then Roster form of $R$ is ...K.... Here, $K$ refers to

${(1, 4), (1, 6), (1, 9)}$

${(1, 4), (1, 6), (2, 9), (3, 4), (3, 6), (5, 9)}$

${(1, 4), (1, 6), (2, 9), (3, 4), (3, 6), (5, 4), (5, 6)}$

None of the above

Difference between $x$ and $y$ is odd, if one of them is odd.
$∴$ In Roster form $R = {(1, 4), (1, 6), (2, 9), (3, 4), (3, 6), (5, 4), (5, 6)}$

Q. Let A={1,2,3,5} and B={4,6,9} and a relation R from A to B is defined by R={(x,y) : the difference between x and y is odd; x∈A and y∈B}. Then Roster form of R is ...K.... Here, K refers to

{(1,4),(1,6),(1,9)}

{(1,4),(1,6),(2,9),(3,4),(3,6),(5,9)}

{(1,4),(1,6),(2,9),(3,4),(3,6),(5,4),(5,6)}
