Question

Match the following: $\begin{array}{cc}\text{Column A}& \text{Column B}\\ \text{1. {1, 2, 4, 8}}& \text{A. x: x is a natural even number less than 10}\\ \text{2. {2}}& \text{B. x: x is a prime number and a divisor of 8}\\ \text{3. {2, 4, 6, 8}}& \text{C. x: x is a divisor of 8}\\ \text{4. {4, 6, 8, 9}}& \text{D. x: x is a composite number less than 10}\end{array}$

• A. 1 - C, 2 - A, 3 - B, 4 - D
• B. 1 - B, 2 - D, 3 - A, 4 - C
• C. 1 - A, 2 - D, 3 - C, 4 - B
• D. 1 - C, 2 - B, 3 - A, 4 - D

Answer 1

The correct option is D

1 - C, 2 - B, 3 - A, 4 - D

{1, 2, 4, 8} is the set of divisors of 8 → (C)

{2} is set of prime number & divisor of 8 → (B)

{2, 4, 6, 8} is set of even numbers less than 10

{4, 6, 8, 9} is the set of composite numbers less than 10
