Question

On dividing 0.46 by 15.374, the actual answer is 0.02992. The correctly reported answer will be:

• A. 0.03
• B. 0.03
• C. 0.029
• D. 0.0299

Answer 1

The correct option is B 0.03

In case of division, the result must be reported with no more significant figures as are there in the measurement with the few significant figures.
$\frac{0.46}{15.734}=0.02992$.
As the least precise term involved has two significant figures (viz. 0.46), therefore reported answer $=0.030$ (two significant figures).
