हिन्दीApplying the standard rules of rounding off to three significant figures, the numbers \( 2.745 \) and \( 2.735 \) become respectively:
Correct answer · Option 1
\( 2.74 \) and \( 2.74 \)
Explanation
If the trailing digit to be dropped is 5, the convention is that if the preceding digit is even, it is left unchanged; if odd, it is raised by 1. For 2.745, preceding digit 4 is even, so it stays 2.74. For 2.735, preceding digit 3 is odd, so it is raised to 2.74.
