Which of the following is an equivalent set? - Infinity Learn by Sri Chaitanya

A
A = { a,b.c,d },B = { d,c,b,a }
B
A = { 4,8,12,16}, B = { 8,4,16,18 }
C
A = { $χ$ : $χ$ is multiple of 10 }
B = { 10,15,20,25,30 }
D
None of these

Solution:

(a) Here, all the elements of the sets $A$ and $B$ are same which are $a, b, c$ and $d$ . Thus, $A$ = $B$ . So , A and B are equivalent set

(b) Here, 12 is an element of $A$ but not the element of $B$ and 18 is an element of $B$ but not the element of $A$ . Thus, all the elements of the sets $A$ and $B$ are not same. Hence, $A$ $\neq$ $B$ .

Clearly, $A$ $\neq$ $B$ as all the elements of the sets $A$ and $B$ are not same.
