Question

Let A and B be two sets such that A × B has 6 elements. If three elements of A × B are {(1, 4), (2, 6),(3, 6)}, then. [ ]

a) A = {1, 2} and B = {3, 4, 6}
b) A = {4, 6} and B = {1, 2, 3}
c) A = {1, 2, 3} and B = {4, 6}
d) A = {1, 2, 4} and B = {3, 6}​

Answer 1

Answer:

c is the answer for the given question

Answer 2

Answer:

Step-by-step explanation:

Since {(1,4),(2,6),(3,6)} are the elements of A×B.

It follows that the elements of set A={1,2,3} and B={4,6}

Hence A×B={(1,4),(1,6),(2,4),(2,6),(3,4),(3,6)}

B×A={(4,1),(4,2),(4,3),(6,1),(6,2),(6,3)}
