In the following, state whether A = B or not:(i) A = {2, 4, 6, 8, 10}; B = {x: x is positive even integer and x ≤ 10}(ii) A = {x: x is a multiple of 10}; B = {10, 15, 20, 25, 30 …}

(i) A = {2, 4, 6, 8, 10};

B = {x: x is a positive even integer and x ≤ 10} = {2, 4, 6, 8, 10}

So, A = B

(ii) A = {x: x is a multiple of 10}

B = {10, 15, 20, 25, 30 …}

We know that 15 ∈ B but 15 ∉ A.

So, A ≠ B
