Here's the Solution to this Question

$A=\{2,3,6,12\}\\ xRy \ iff \ 2|x-y\\ R=\{(2,3),(3,2)\}\\ xSy \ iff \ 3|x-y\\ S=\{(2,3),(3,2),(3,6),(6,3)\}\\ R^{-1}=\{(3,2),(2,3)\}\\ R\cap S=\{(2,3),(3,2)\}\\ R\cup S=\{(2,3),(3,2),(3,6),(6,3)\}\\ S^{-1}=\{(3,2),(2,3),(6,3),(3,6)\}$ $A = {2, 3, 6, 12} x R y i ff 2∣ x - y R = {(2, 3), (3, 2)} x S y i ff 3∣ x - y S = {(2, 3), (3, 2), (3, 6), (6, 3)} R^{- 1} = {(3, 2), (2, 3)} R \cap S = {(2, 3), (3, 2)} R \cup S = {(2, 3), (3, 2), (3, 6), (6, 3)} S^{- 1} = {(3, 2), (2, 3), (6, 3), (3, 6)}$
