What is the value of the number $96378$ when rounded off to two significant figures?

Assertion $(A)$: The number $0.00764$ has three significant figures.
Reason $(R)$: If the number is less than $1$,the zeros on the right of the decimal point but to the left of the first non-zero digit are not significant.

An object of mass $m = 3.513 \ kg$ moves along the $x$-axis with a velocity of $5.00 \ ms^{-1}$. The magnitude of its momentum can be recorded as $...... \ kg \ ms^{-1}$.

$5.74 \; g$ of a substance occupies $1.2 \; cm^3$. Express its density (in $g/cm^3$) by keeping the significant figures in view.

If a calculated value $2.7465 \,g$ contains only three significant figures,the two insignificant digits in it are ............

Match the measurements given in List-$I$ with the number of significant figures given in List-$II$.

$A$. $74.083$	$I$. $3$
$B$. $0.029$	$II$. $4$
$C$. $0.002407$	$III$. $2$
$D$. $2.74 \times 10^7$	$IV$. $5$

The correct answer is:
