Q. 14

# If U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} and A = {2, 5, 6, 9, 10} then A’ is

A. {2, 5, 6, 9, 10}

B. Φ

C. {1, 3, 5, 10}

D. {1, 3, 4, 7, 8}

Answer :

**Given,**

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} and A = {2, 5, 6, 9, 10}

We have to find A’ (A compliment)

A’(A compliment) means we have to find the eliminate the elements of sets A in U.

∴ A’ = {1, 3, 4, 7, 8}

Option D is the correct answer.
