A man bought a second hand photocopying machine for ₦34,000. He serviced it at a cost of ₦2,000 and then sold it at a profit of 15%. What is the selling price?

The total cost price of the photocopying machine is $₦34,000 + ₦2,000 = ₦36,000$. The man sold it at a profit of $15 \%$ so the selling price will be $\frac{100+15}{100} \times 36000 = ₦41400$
