If n(A) = 25, n(B) = 40, `n(AcupB)=50` and n(B') = 25, find `n(AcapB)` and n(U).

(i)If n(A)=25, n(B)=40, n(A cup B)=50 and n(B')=25," find "n(A cap B) and n(U) . (ii) If n(A)=300, n(A cup B)=500, n(A cap B)=50 and n (B')=350 , find n(B) and n(U) .

If n(A) = 300, n(AcupB)=500,n(AcapB)=50 and n(B') = 350, find n(B) and n(U).

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

If n(A) = 30 , n(B') = 6 , n(A nn B) = 25 and n(B-A) = 37 , find n(B) , n(U) , n(A uu B) and n(A - B)

If n(A nn B) = 40, n(A) = 50 and n(B) = 60 , then find n(A DeltaB)

If n(A) = 12, n(B) = 17 and n(AcupB)=21" find "n(AcapB) .

If n(A uu B) = 50 , n(A) = 31 and n(B) = 23 , find n(A nn B) , n(A-B) and n(B-A)
