Which of the following are pairs of equal sets?
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.
