Question

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

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

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

3. {2, 4, 6, 8} is set of even numbers less than 10 → (A)

4. {4, 6, 8, 9} is the set of composite numbers less than 10 → (D)
