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

If n(A)= 7, n(B)= 13, n(A cap B) = 4 , then n(A cup B) = ?

For sets A and B , n(A) = 20 , n(B) = 30 , n (A cup B) = 40 , n (A cap B) = 10 and n(U) = 100 then n(A' cap B') = 60 .

If n(U) = 700, n(A) = 200, n(B) = 240, n (A cap B) = 100, then n(A' cup B') equals
