1.	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.’
Answer» 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.

Answer»

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.
