Question

Let A = {1, 3, 5} and B = {x : x is an odd natural number less than 6}. Then, which of the following are true?

Options

• A ⊂ B

• B ⊂ A

• A = B

• A ∉ B

Answer 1

A = B

Explanation:

A = {1, 3, 5}

B = {x : x is an odd natural number less than 6} – {1, 3, 5}

Since, every element of A is in B, so A ⊂ B.

Every element of B is in A, so B ⊂ A.

Then, A = B.
