Question

Let A = {1, 3}, B = {1, 5, 9}, C = {1, 3, 5, 7, 9}. Then ___________

(a) A⊂B

(b) B⊂A

(c) C⊂B and A⊂C

(d) B⊂C and A⊂C

The question was posed to me in an international level competition.

I need to ask this question from Subsets topic in division Sets of Mathematics – Class 11

Answer 1

Correct option is (d) B⊂C and A⊂C

The best I can explain: Here A has two elements 1 and 3. They both belongs to C so, A⊂C.                                                                                                                     Here B has three elements 1, 5 and 9. They all belongs to C so, B⊂C.
