TNPSC Group-I 2025 · Question 65 of 66

If a != b != c is given, which one of the following is correct?

Aptitude - Logical Reasoning

  1. Ab != a != c
  2. Ba, b, c are distinct
  3. Ca = b = c
  4. Da != c or a = cCorrect

Answer: D. a != c or a = c

Explanation

'a is not equal to b is not equal to c' asserts only a!=b and b!=c; 'a!=c or a=c' is a tautology and therefore always correct.
