Here's the Solution to this Question

Let A = \{2,4\} and B = \{6,8,10\} and define relations R and S from A to B as follows:


For all (x, y) \in A \times BxRy iff x|y, and xSy iff y - 4 = x.


Let us state explicitly which ordered pairs are in A \times B, R, S, R\cup S, and R\cap S:


A\times B=\{(2,6),(2,8),(2,10),(4,6),(4,8),(4,10)\}


R=\{(2,6),(2,8),(2,10),(4,8)\}


S=\{(2,6),(4,8)\}


R\cup S=\{(2,6),(2,8),(2,10),(4,8)\}


R\cap S=\{(2,6),(4,8)\}
