The correct answer is:
$2.74$ and $2.74$
Rounding off $2.745$ upto 3 significant figures here IV th digit is 5 and its preceding is even, so no change in 4. Thus answer would be $2.74$. Rounding off $2.735$ upto 3 significant figures, here IV digit is 5 and its preceding digit is 3 (odd). So 3 is increased by 1 answer become would be $2.74$.
