CBSE · Class 11 · Mathematics · Relations and FunctionsIf $A \times B = \{(a, x), (a, y), (b, x), (b, y)\}$, find $A$ and $B$.
Step-by-Step Solution
The set $A$ consists of all first elements of the ordered pairs in $A \times B$, so $A = {a, b}$. The set $B$ consists of all second elements of the ordered pairs in $A \times B$, so $B = {x, y}$. Therefore, option A is correct.
