Question

What per cent of $Rs.4500$ is $Rs.9000$?

(a) $200\%$
(b) $\frac{1}{2}\%$
(c) $2\%$
(d) $50\%$

Answer 1

Let $x\%$ of $Rs.4500=Rs.9000$

$\Rightarrow \frac{x}{100}\times Rs.4500=Rs.9000$

$\Rightarrow 45x=9000$

$\Rightarrow x=\frac{9000}{45}$

$\Rightarrow x=200$

i.e., $200\%$ of $Rs.4500$ is $Rs.9000$.

Hence, Option (a) is correct.
