1.	Let `A = {1, {2, 3}, 4}`. Then, which of the following statements is true ? (i) `{2,3} in A` (ii) `{2,3} subset A` Rectify the wrong statement.
Answer» Clearly, A is a set containing three elements, namely 1, {2,3} and 4. (i) `{2, 3} in A` is a true statement. (ii) `{2, 3} subset A` is wrong. On rectifying this statement, we get `{{2,3}} subset A` as true statement.
