If A and B are two sets so that  `n(B - A)= 3n(A-B) = 9n(AcapB)` and if `n(AcupB) = 26`, find n(p(A)).

If A and B are two sets so that n(B - A) = 2n(A - B) = 4n(Acap B) and if n(AcupB) = 21 . Find n(p(B))

If A and B are two sets so that n(B- A) = 2n (A-B) = 4n (A cap B) and if n(A cup B)= 14 then find n(P(A))

If A and B are two sets so that n(B-A) =2n (A-B) =4n(A cap B) and" if "n(A cup B)=14 , then find n(P(A)).

If A and B are two sets, then n(A)+ n(B) is equal to
