Let `n(A-B)=25+x, n(B-A)=2x` and `n(A nn B)=2x`, If `n(A)=2(n(B))` then `x=`

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) =

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 .

Let A,B,C are three sets such that n(A)=25,n(B)=20,n(C)=27,n(A nn B)=5,n(B nn C)=7andA nn C=varphi the nn(A uu B uu C)60.653.674.725.56

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) .

If n(A nn B')=5 ,n(B nn A')=6 ,n(A nn B)=4 then the value of n(A uu B) is
