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 …}
In the following, state whether A = B or not:

(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 …}

(i) A = {a, b, c, d}; B = {d, c, b, a}
The order in which the elements of a set are listed is not significant.
∴ A = B
(ii) A = {4, 8, 12, 16}; B = {8, 4, 16, 18}
It can be seen that 12 ∈ A but 12 ∉ B.
∴ A ≠ B
(iii) A = {2, 4, 6, 8, 10}
B = {x: x is a positive even integer and x ≤ 10}
= {2, 4, 6, 8, 10}
∴ A = B
(iv) A = {x: x is a multiple of 10}
B = {10, 15, 20, 25, 30 …}
It can be seen that 15 ∈ B but 15 ∉ A.
∴ A ≠ B
`(i)` – Both sets `A` and `B` are having same elements. Only order is different that means `A=B`.
`(ii)` – Set `A` contains 12 that is not present in Set `B` and Set `B` contains 18 that is not present in Set `A`. So, `A!= B`.
`(iii)` – Set `A` contains 10 that is not present in Set `B` as Set `B` contain all elements less than 10.So, `A!= B`.
`(iv)` – Set `B` contains 15,25 etc. that are not multiple of 10.So, `A!= B`.
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, -}.
(v) A = {x: x is a prime numbers ≤ 6}, B = {x: x is a prime factors of 30}.
