Q86 / 180 · NEET 2020 (Phase 1) · Physics

Taking into account of the significant figures, what is the value of $9.99 m - 0.0099 m$ ?

Correct answer
A
$9.98 m$
B
$9.980 m$
C
$9.9 m$
D
$9.9801 m$

Solution

In subtraction the number of decimal places in the result should be equal to the number of decimal places of that term in the operation which contain lesser number of decimal places.

$\frac{\begin{matrix} 9 .99 \\ - 0 .0099 \end{matrix}}{9 .98}$

$\Rightarrow 3$ siginificant figures

Hence, the correct answer is option: 'A'.
