If $A = \{2, 3, 5\}, B = \{2, 5, 6\},$ then $(A -B) × (A \cap B)$ is
$\{(3, 2), (3, 3), (3, 5)\}$
$\{(3, 2), (3, 5), (3, 6)\}$
$\{(3, 2), (3, 5)\}$
None of these
If $A \times B =\{(p, q),(p, r),(m, q),(m, r)\},$ find $A$ and $B$
Let $A=\{1,2\}, B=\{1,2,3,4\}, C=\{5,6\}$ and $D=\{5,6,7,8\} .$ Verify that
$A \times C$ is a subset of $B \times D$
$A = \{1,2,3,4......100\}, B = \{51,52,53,...,180\}$, then number of elements in $(A \times B) \cap (B \times A)$ is
