ans

- \( A = \{6, 12, 18, 24, 30, 36, 42\} \)

- \( B = \{1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29\} \)

- \( C = \{5, 15, 25, 35, 45\} \)

- \( A' - B = \{33, 39, 45\} \)

- \( B \cup C = \{1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 35, 45\} \)

- \( A \cap C \cup B = \{1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29\} \)
