Significant Figures & Order of Magnitude

For an experimental expression $y = \frac{32.3 \times 1125}{27.4}$ , where all the digits are significant. Then to report the value of $y$ we should write

Show answer and solution

Answer: (d)

$y = \frac{32.3 \times 1125}{27.4} = 1326.186$
Least significant figures among the data: 3 (32.3 and 27.4).
Rounded to 3 significant figures: $y = 1330$
So the answer is (d).
