In the following, state whether `A = B`or not:(i) `A = {a , b , c , d}` `B = {d , c , b , a}`(ii) `A = { 4, 8, 12 , 16 }` `B = {8, 4, 16 , 18}`(iii) `A = {2, 4, 6, 8, 10}` B = {x: x is positive even integer and x≤10} (iv) A = {x : x is a multiple of 10} B={10,15,20,25,30,...}

Explanation

To determine whether the sets A and B are equal in each case, we need to check if they contain exactly the same elements. Two sets are considered equal if every element of set A is also in set B and vice versa.

Let's analyze each case step by step:

### (i)
**Given:**
- A = {a, b, c, d}
- B = {d, c, b, a}
