It should be 3mL² if the mass of each rod is m and not mL² as you have written.

Sir I'm also getting 3ml² but in FIITJEE solution they have used ml2. I don't understand how .

ml²/3 + (ml²/3 + ml²) + (ml²/3 + ml²) = 3ml²
Am I right Sir ??

Anyways.....is then Fiitjee's soln. wrong ?

Obviously the FIITJEE solution is wrong. And that's not a new thing. (They might have m as the total mass though.)
