Question:
Which of the following are pairs of equal sets?
A = set of letters in the word, ‘ALLOY.’
B = set of letters in the word, ‘LOYAL.’
Solution:
Equal Sets = Two sets A and B are said to be equal if they have exactly the
same elements & we write A = B
We have,
A = set of letters in the word, ALLOY
A = {A, L, O, Y}
and B = set of letters in the word, LOYAL
B = {L, O, Y, A}
Here, A = B because the elements in both the sets are equal. The repetition of elements
in a set does not change a set.
Thus, A and B are equal sets.
