Which of the following sets are comparable?(a) A = { 2, 4, 6} and B = { 1, 3, 5, 6} (b) A = { x : x = 4n, n∈ N, n ≤3} and B = { x : x = 2n, n∈ N and n ≤6} (c) A = { a, e, i, o, u } and B = { a, e, i, { o, u}} (d) None of these

Answer»

A = { \(x\) : \(x\) = 4n, n∈ N and n ≤ 3}

= { 4, 8, 12 }

B = { \(x\) : \(x\) = 2n, n∈ N and n ≤ 6}

= { 2, 4, 6, 8, 10, 12}

Here A ⊂ B

⇒ A and B are comparable.
