To find the average yearly profit, we need to sum up the profits for the four years and then divide it by the number of years:
Sum of profits = 20000 + 25000 + 10000 + 5000 = 60000 naira
Number of years = 4
Average yearly profit = Sum of profits / Number of years = 60000 / 4 = 15000 naira
Therefore, the average yearly profit is 15000 naira.
