Free Practice Questions for Percentage in Maths

$2.5$ किग्रा का $x \%=2$ क्विन्टल
$
\begin{aligned}
&\Rightarrow \quad 2.5 \times \frac{x}{100}=200 \\
&\Rightarrow \quad x=\frac{200 \times 100}{2.5} \Rightarrow x=8000 \%
\end{aligned}
$

$\begin{aligned} \frac{7}{8} &=\frac{x}{100} \\ x &=\frac{7 \times 100}{8} \\ &=\frac{175}{2}=85 \frac{1}{2} \end{aligned}$

$3 \frac{4}{7}$ का $56 \%=\frac{25}{7}$ का $56 \%$
$=\frac{25}{7} \times \frac{56}{100}=2.00$

अभीष्ट प्रतिशत $\ =\left(\frac{8 \%}{5 \%} \times 100\right) \% $
$=\left(\frac{8 / 100}{5 / 100} \times 100\right) \%=\left(\frac{8}{5} \times 100\right) \%=160 \% $

$x$ का $7 \frac{1}{2} \%=150$
$\Rightarrow \quad x \times \frac{15}{2 \times 100}=150 \Rightarrow x=\frac{150 \times 2 \times 100}{15}$
$\Rightarrow \quad x=2000$

$\ 350$ का $60 \% =x \times 15$
$=350 \times \frac{60}{100}=x \times 15 $
$=210=x \times 15 $
$x =\frac{210}{15} $
$x =16 $
