The profit

The profit made by a business in 2018 was triple that made in 2019. The profit made in 2020 was R 3 million less than the profit made in 2019. If the total profit in these 3 years was R 67 million, what was the profit made in 2020?

Correct answer:

c =  11000000

Step-by-step explanation:

$$\begin{gathered} a=3\cdot b \\ c=b-3000000 \\ a+b+c=67000000 \\ a-3b=0 \\ b-c=3000000 \\ a+b+c=67000000 \\ a=42000000 \\ b=14000000 \\ c=11000000 \end{gathered}$$
