Subset

If $\mathrm{A}=\{a,b,c,d,e\}$, the number of elements of the power set of $\mathrm{A}$ is 

The number of proper subsets of the set $\{a, b, c, d, e, f, g\}$ is

If $A$ is a finite set having $n$ elements, then the power set $P\left(A\right)$has 

If $A$ and $B$ are two sets such that $n\left(A\right)=12, n(A-B)=5$ and $n(A\cup B)=23$, then maximum number of subsets of $A\cap B$ is 

Let $A$ and $B$ are two sets with $m$ and $n$ elements, respectively. If the number of subsets of first set is $56$more than the number of subsets of the second set, then $(m, n)$ is

If the number of non-empty subsets of a set is $4095$, the number of elements of the set is
