S = {1, 2, 3, 4, 5, 6}, T = {2,4,5,7} and R = {1,4, 5}, and (S∩T) ∪ R

  • A.
    {1, 4, 5}
  • B.
    {2, 4, 5}
  • C.
    {1, 2, 4, 5}
  • D.
    {2, 3, 4, 5}
  • E.
    {1, 2, 3, 4, 5}
Correct Answer: Option C
Explanation

S = {1, 2, 3, 4, 5, 6};  T = {2, 4, 5, 7}; R = {1, 4, 5}

(S∩T) ∪ R = {2, 4, 5}  ∪ {1, 4, 5}

= {1, 2, 4, 5}
