The shaded region in the given figure is:

If $A = \{x : x \text{ is a multiple of } 3\}$ and $B = \{x : x \text{ is a multiple of } 5\}$,then $A - B$ is ($\bar A$ denotes the complement of $A$).

$A$ set contains $2n + 1$ elements. The number of subsets of this set containing more than $n$ elements is equal to

If $A = \{x : x \text{ is a multiple of } 4\}$ and $B = \{x : x \text{ is a multiple of } 6\}$,then $A \cap B$ consists of all multiples of

The domain of the function $\sqrt{\log \left( \frac{5x - x^2}{6} \right)}$ is

If $n(A) = 3$ and $n(B) = 6$ and $A \subseteq B$,then the number of elements in $A \cap B$ is equal to
