On natural numbers, (aRb) is defined when (b=3a). Is this relation transitive?

Answer and explanation

Correct answer: Not transitive

Step 1: (1R3) is true because (3=3\cdot 1), and (3R9) is true because (9=3\cdot 3). Step 2: Transitivity would require (1R9), but (9\ne 3\cdot 1). Step 3: Applying a rule twice does not necessarily make the direct rule true.
