Which of the following are pairs of equal sets?

C = set of letters in the word, ‘CATARACT.’


D = set of letters in the word, ‘TRACT.’


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,


C = set of letters in the word, ‘CATARACT.’


C = {C, A, T, R}


and D = set of letters in the word, ‘TRACT.’


D = {T, R, A, C}


Here, C = D because the elements in both the sets are equal. The repetition of elements in a set does not change a set.


Thus, C and D are equal sets.
