Jambmaths question: 

A man brought a second – hand photocopy machine for N34,000. He serviced it at a cost of N2,000 and sold it a profit of 15%. What was the selling price?

Jamb Maths Solution: 

$\begin{align}  & \frac{profit}{Total\text{ }\cos t\text{ }price}\times 100percent=Percentage\text{ }profit \\ & \frac{profit}{34000+2000}\times 100=15 \\ & \frac{profit}{36000}\times 100=15 \\ & profit=\frac{36000\times 15}{100}=5400 \\ & selling\text{ }price=Total\text{ }\cos t\text{ }price+profit \\ & selling\text{ }price=36000+5400=41400 \\\end{align}$
