Am I a doodoo brain or highly intellect for this

Answer choices are 18, 20, 23, 26, 30

I simply calculated the fine (181) over the average times he gets caught (1/10). The final answer is 18.1, which is the amount he needs to steal each time to not lose profit. Of course, 18 is a net loss of 1 euro every time he gets caught, so the next closest answer was 20, and I picked it. If there was an answer such as “19” would this be the better answer?

One more note, In the solutions, it was mentioned that alot of people get this wrong by picking C (23). Just wanted more clarification on that, obviously weird im asking how to solve to get the wrong answer but definitely my way of thinking was not the way why many people got this question wrong as they pick C, if I were to get this wrong I would’ve chosen A (18)

thank you!

Read the statement below. (BTW: when …)
This should clarify the approach (18.1 per attempt is incorrect).

Based on the correct approach, people would generally choose option C as 23 is greater than the amount you get when you solve it.
However, since it’s stated ‘approximate’, we must choose the answer that is closer to the calculated answer, which is 20, hence option B.
