(D) Let the number be $x$.Given that $42 \%$ of $x = 357$.$\frac{42}{100} 	imes x = 357$.$x = \frac{357 	imes 100}{42}$.Now,we need to find $63 \%$ of $x$.$63 \%$ of $x = \frac{63}{100} 	imes x$.Substituting the value of $x$:$= \frac{63}{100} 	imes \left( \frac{357 	imes 100}{42} ight)$.$= \frac{63 	imes 357}{42}$.Dividing $63$ and $42$ by $21$,we get $\frac{3}{2} 	imes 357$.$= \frac{1071}{2} = 535.5$.

$42 \%$ of a number is $357$. What is $63 \%$ of that number?
