Question

Let X be the set {1, π, {42, √2}, {1,3}}. Which of the following statement(s) is/are true? Ρ : π ∈X , Q :{1,3} ⊆ X , R : {1,7} ⊆ X 

• A. P and R only
• B. Q only
• C. R only
• D. P only
• E. P, Q and R

Answer 1

The Correct Option is D

The correct answer is P only.

Step-by-step Explanation: 

The set X is defined as {1, π, {42, √2}, {1, 3}}. We will now evaluate each of the given statements (P, Q, R) one by one:

• Statement P: π ∈ X
• Statement Q: {1, 3} ⊆ X
• Statement R: {1, 7} ⊆ X

Conclusion:

Only the statement P (π ∈ X) is true, so the correct answer is P only.
