If A={y:|y|=3x,x≤2,x∈N}, B={x:x is a positive even number,x<14} and C={1,4,8}, then n((A×B)∩(A×C)) is
If n(A - B) = 36, n(B - A) = 40 and n (A∩B)=24, then n (A∪B)= ___
A and B are two sets such that n (A - B) =14 + x, n(B - A) = 3x and n(A ∩ B) = x.
Draw a Venn diagram to illustrate information and if n(A) = n(B), then find the value of x.
