Correct Answer

C

Explanation

Total cost = 34,000+#2,000=36,00015% = 100 #5therefore 115 /100 x #36,000To find the selling price of the second-hand photocopying machine, we need to calculate the profit and add it to the total cost.The man bought the photocopying machine for N34,000 and then spent N2,000 on servicing it. Therefore, the total cost of the machine is N34,000 + N2,000 = N36,000.To calculate the profit, we need to find 15% of the total cost. We can do this by multiplying the total cost by 0.15:Profit = 0.15 * N36,000 = N5,400Finally, to find the selling price, we add the profit to the total cost:Selling price = Total cost + Profit = N36,000 + N5,400 = N41,400Therefore, the selling price of the second-hand photocopying machine is N41,400.= #41,400
