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) = 25+ x, n(B) = 27 -x and n(B) = 27-x and n(A uu B) = 46 , then n (A Delta B) =

Let n(U) = 700 , n (A) = 200 , n (B) = 300 and n (A nn B) =100, then n(A' nn B') =

If A and B are two sets that n(A-B)=14+x in n(A)=n(B) and n(B-A)=3x and also n(A nn B) =x .Then x is equal to a."8," b."7," c."9," d.None of these

If n(A)=x, n(B)=2[n(A)], n(A uu B)=2017 and n(A nn B)=1007 . Find the value of x .

If n ( A nn B') = 2x + 40, n(A nn B) = x+10 and n(B nn A') = 60-3x , then find n(A uu B) .
