Question

A= {P, O, L, Y, T, E, C, H, N, I, Q), B= {P, O, L, Y, C, E, T, 2020), B-A=

• A. {20}
• B. {2020}
• C. {40}
• D. None

Answer 1

The Correct Option is B

To solve this problem, we need to find the difference between the sets \( B \) and \( A \), denoted as \( B - A \).

1. Given Sets:
\( A = \{ P, O, L, Y, T, E, C, H, N, Q \} \)
\( B = \{ P, O, L, Y, C, E, T, 2020 \} \)

2. Finding \( B - A \):
The set difference \( B - A \) consists of elements in \( B \) that are not in \( A \).
Looking at both sets, the only element present in \( B \) but not in \( A \) is \( 2020 \).

3. Conclusion:
\( B - A = \{ 2020 \} \)

Final Answer:
The correct option is (B) \(2020.\)
