Question

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

• 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
