Option D:

Jamb Maths Solution:
$\begin{align} & Percent\text{ }profit=\frac{profit}{\cos tprice}\times 100percent \\ & Percent\text{ }profit\text{ }for\text{ }femi=\frac{10000}{\cos tprice}\times 100percent=40percent \\ & \cos t\text{ }price=\frac{10000}{0.4}=N25000 \\ & Selling price from Audu=N25000 \\ & loss=selling price-\cos t price=N50000-N25000 \\ & loss=N25000 \\ & Percentage\text{ }loss=x=\frac{loss}{\cos tprice}\times 100=\frac{25000}{50000}\times 100percent \\ & x=50percent \\\end{align}$
