Q. For an experimental expression $y=\frac{32.3\times1125}{27.4}$, where all the digits are significant. Then to report the value of $y$ we should write
A) $y=1326.19$
B) $y=1330$
C) $y=1326.186$
D) $y=1326.2$
Explanation
[Solution by Dr. Abubacker] The calculated value is $1326.186\ldots$. The least number of significant figures among the data is $3$ (32.3 and 27.4), so the result is reported with 3 significant figures: $1330$. Answer (2).
