Tick (✓) the correct answer

Question:

Tick (✓) the correct answer:

(180% of ?) ÷ 2 = 504

(a) 400

(b) 480

(c) 600

(d) 560

Solution:

(d) 560

Let the required number be $\mathrm{x}$. Then, we have :

$(180 \%$ of $x) \div 2=504$

$\Rightarrow\left(x \times \frac{180}{100}\right) \div 2=504$

$\Rightarrow\left(\frac{180 x}{100}\right) \div 2=504$

$\Rightarrow\left(\frac{180 x}{100} \times \frac{1}{2}\right)=504$

$\Rightarrow \frac{9 x}{10}=504$

$\Rightarrow x=\left(504 \times \frac{10}{9}\right)$

$\Rightarrow x=560$
