If `n(A times B)=6` and `A={1,3}` then n(B) is

(a) If n(A) = 6 and n(AxxB)=42 then find n(B) (b) If some of the elements of A xx B are (x,p),(p,q), (r,s) . Then find the minimum value of n(A xx B) .

If n(A) denotes the number of elements in set A and if n(A) = 4, n(B) = 5 and n(A nn B) =3 then n[(A xx B) nn (B xx A)]=

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

If n (A Delta B) = 12 and n(A nn B) = 3 , then find the greatest possible value of n(A xx B) .

If n(A nn B)=3,n(A)=5,n(B)=4, then n(A xx B)+n(A uu B)20 b.9 c.26d .none of these

If n(A)=7,n(B)=6 and 1<=n(A nn B)<=4, then number of elements in the range of (A Delta B) is

If n(A)=6 and n(B)=3, then find the number of subsets of A xx B .

If n(A xx B) = 24, n(B xx C) = 36 , and n(B) = 3 , then n(A xx C) =

If A={a,b}. Then n(A times A) is :
