Question

After rounding off 1.235 and 1.225 to two places, the answer will be :

• A. 1.23, 1.22
• B. 1.24, 1.123
• C. 1.23, 1.23
• D. 1.24, 1.22

Answer 1

The correct option is D 1.24, 1.22

lf the digit just next to the last digit to be retained is $5$, then the last significant figure is left unchanged if it is even and is increased by $1$ if it is odd.

Hence, $1.235=1.24$ and $1.225=1.22$

So, option D represents the correct answer.
