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 was the selling price?
Worked solution (try it first)
The cost includes the servicing: 34000+2000= ₦36,000.
A 15% profit means selling for 115% of the cost: 1.15×36000=41400.
