(B) Given that $90 \%$ of $A = 30 \%$ of $B$.This can be written as $\frac{90}{100} 	imes A = \frac{30}{100} 	imes B$.Simplifying the equation,we get $90A = 30B$,which implies $B = \frac{90}{30} A = 3A$.We are also given that $B = x \%$ of $A$,which means $B = \frac{x}{100} 	imes A$.Equating the two expressions for $B$,we have $3A = \frac{x}{100} 	imes A$.Dividing both sides by $A$ (assuming $A 
eq 0$),we get $3 = \frac{x}{100}$.Therefore,$x = 3 	imes 100 = 300$.

If $90 \%$ of $A = 30 \%$ of $B$ and $B = x \%$ of $A$,then the value of $x$ is
