Match List-I with List-II
| List-I | List-II |
|---|---|
| (A) The number π is a/an | (I) whole number |
| (B) 0 is a/an | (II) complex number |
| (C) √(−1) is a/an | (III) composite number |
| (D) 6 is a/an | (IV) irrational number |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
π cannot be written as a ratio of two integers and its decimal never repeats, so it is an irrational number (A - IV). 0 is the first of the whole numbers (B - I).
√(−1), written as i, is not a real number at all and belongs to the complex numbers (C - II), while 6, having factors besides 1 and itself, is a composite number (D - III).
