If $A = \{1, 2, 3, 4, 5\}, B = \{2, 4, 6\}, C = \{3, 4, 6\},$ then $(A \cup B) \cap C$ is
$\{3, 4, 6\}$
$\{1, 2, 3\}$
$\{1, 4, 3\}$
None of these
Let $A=\{1,2,3,4,5,6\}, B=\{2,4,6,8\} .$ Find $A-B$ and $B-A$
If $A, B, C$ be three sets such that $A \cup B = A \cup C$ and $A \cap B = A \cap C$, then
If $X=\{a, b, c, d\}$ and $Y=\{f, b, d, g\},$ find
$Y-X$
If $A, B$ and $C$ are any three sets, then $A - (B \cap C)$ is equal to
Show that $A \cap B=A \cap C$ need not imply $B = C$
