Question

Which of the following statement is false?

(a) 24 is even number or odd number

(b) 15 is prime or divisible by 3

(c) 71 is odd number or prime

(d) Japan or China is in India

This question was addressed to me during an online exam.

This intriguing question comes from Mathematical Reasoning topic in section Mathematical Reasoning of Mathematics – Class 11

Answer 1

The correct answer is (d) Japan or China is in India

For explanation I would say: 24 is even number so “24 is even number or odd number” is correct.                                                                                                              15 is divisible by 3 so “15 is prime or divisible by 3” is true.                                                                                                                                            71 is prime as well as odd so “71 is odd number or prime” is true.                                                                                                              Neither Japan nor China is in India so “Japan or China is in India” is false.
