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 < x ≤ 6}


B = {x: x is a natural number and 6 < x < 10}


(v) A = {1, 2, 3}, B = ϕ

(i) It is given in the question that,


X = {1, 3, 5}


And, Y = {1, 2, 3}


∴


(ii) It is given in the question that,


A = {a, e, i, o, u}


And, B = {a, b, c}


∴


(iii) It is given in the question that,


A = {3, 6, 9, 12, 15, 18,……}


And, B = {1, 2, 3, 4, 5}


∴


(iv) It is given in the question that,


A = {2, 3, 4, 5, 6}


And, B = {7, 8, 9}


∴


(v) It is given in the question that,


A = {1, 2, 3}


And,


∴
