Let A and B be two sets such that
`AxxB = {(a, 1), (b, 3), (a, 3), (b, 1), (a, 2), (b, 2)}`
Then,

A

A = {1, 2, 3} and B = {a, b}

B

A = {a, b} and B = {1, 2, 3}

C

A = {1, 2, 3} and `B sub {a, b}`

D

`A sub {a,b} and B sub {1, 2, 3}`

Text Solution

Verified by Experts

The correct Answer is:
B
Clearly, A is the set of all first elements in ordered pairs in `A xx B` and B is the set of all second elements in `A xx B`
`therefore A = {a, b} and B = {1, 2, 3}`.
