`2n(A\B)=n(B\A)` and `5(A cap B)=n(A)+3n(B)`

For sets A and B, n(A - B)= 8+2x, n(B - A)= 6x" and "n(A cap B)= x . If n(A)= n(B) then n(A cap B)="……….."

If n(A)=8,n(B)=6 and n(A cap B) = 3 , then n(A cup B) = ?

If n(A)=8,n(B)=6 and n(A cap B) = 3 , then n(A cup B) = ?

n(A)=2,n(B)=7, n(A cap B)=1 and n (A cup 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))

n(A)=20, n(B)=18 and n(A cap B)=5 , then n(A cup B) is

n(A)=20, n(B)=18 and n(A cap B)=5 , then n(A cup B) is

If n(A) = 35, n (B) = n(B) = 40 and n(A cup B) = 50, find n(A cap B) .

IF n(A)=8,n(B)=6, n(A cap B)=3, then n(A cup B)=………

If A and B are two sets such that n (A)=27, n(B)=35 and n(A cup B) =50 . Find n(A cap B) .
