Find the union of each of the following pairs of sets :
(i) `X = {1,3,5} " " Y={1,2,3}`
(ii) `A = {a,e,i,o,u}" "B={a,b,c}`
(iii) A = {x : x is a natural number and multiple of 3}
B = {x : x is a natural number less than 6}
(iv) A = {x : x is a natural number and `1 lt x le 6`}
B = {x : x is a natural number and `6 lt x lt 10`}
`A = {1,2,3}, B = phi`.
