Example 8, Which of the following pairs of sets are equal? Justify your answer. (i) X, the set of letters in “ALLOY” and B, the set of letters in “LOYAL”. X = {A, L, L, O, Y}, but L is repeated. So, X = {A,L,O,Y} B = {L, O, Y, A, L}. but L is repeated. So, B = {O,Y, A,L} Elements of set A = A, L, O, Y Elements of set B = O, Y, A, L Every element of X is same as every element of B. ∴ X = B
