Numerical reasoning tests are hard. Usually the first time we encounter them is when we apply for a job. For that reason, numerical reasoning tests are feared. But how hard are they, and what is the hardest numerical reasoning question ever written?
We’ve been through thousands of numerical reasoning questions and millions of answers to find the one. The needle in the haystack. The numerical reasoning question that no-one can answer. And here it is:
Q) If the rates change in 2025 by the same amount as in 2024 and manufacturing costs do not change, what will the manufacturing cost be in Brazilian Reals?
Correct Answer: C.
Step 1. Brazilian Reals by 0.05 between 2023 and 2024. Therefore, the rate will be 2.85 in 2025
Step 2. Calculate manufacturing cost in Reals = 2.85 X 4.5 = 12.83
478 takers, 158 correct, 320 wrong, 33% success
So there you go - that was the hardest numerical reasoning question ever written. Just 33% of people got that one right so don’t feel bad if you were one of them. However, if you’d like to stand out from the crowd, it might be time to start practicing.
