Question

U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. Which of the following is not a subset of the universal set?

(a) {1,2}

(b) {0,1,2,3,4,5,6,7,8,9}

(c) {2,3,5,7}

(d) {1,2,3,4,5,6,7,8,9,10}

The question was asked during an online exam.

I'm obligated to ask this question of Universal Set in chapter Sets of Mathematics – Class 11

Answer 1

Correct choice is (d) {1,2,3,4,5,6,7,8,9,10}

For explanation: In {1,2,3,4,5,6,7,8,9,10}, 10 is not present in set U. So, it is not the subset of universal set. Rest all are subsets of set U as their elements are present in universal set.
