MCQ
For an experimental expression $\mathrm{y}=\frac{32.3 \times 1125}{27.4}$, where all the digits are significant. Then to report the value of $y$ we should write :-
  • A
    $y=1326.2$
  • B
    $y=1326.19$
  • C
    $y=1326.186$
  • $y=1330$

Answer

Correct option: D.
$y=1330$
(D)
Sol. $\mathrm{y}=\frac{32.3 \times 1125}{27.4}=1326.186$
Last significant digits are 3 in operands so results should rounded off to 3 digits.
$\therefore \mathrm{y}=1330$
