Based on the data in the table about innovation and economy indicators in the European Union for the year 2015, what is the approximate value of the 'Patents per Million Euros Invested in R&D' ratio for the country that recorded the highest absolute R&D investment that year? Keep in mind that the ratio should be calculated by dividing the total number of patents by the total R&D expenditure (in millions of euros) for that specific country. option_A: 24.8 option_B: 18.2 option_C: 31.4 option_D: 12.5 option_E: None of the above Explanation: Hello, I am EUgenio. We will break down this problem to help you master EPSO numerical reasoning. 1) Why the correct answer is E: First, we need to identify the country with the highest absolute R&D investment. By reviewing the 'R&D Investment (M €)' column, we see that Germany has 15,400 million euros, which is the highest value on the list. Then, we look for the number of patents for Germany in the 'Patents (thousands)' column, which is 380,000. The ratio is calculated by dividing the total number of patents by the R&D expenditure (in millions of euros): 380,000 / 15,400 ≈ 24.675. Rounding to one decimal place, we get 24.7. Since none of the numerical options (A, B, C, D) match this precise calculation, and option E is 'None of the above', this is the correct answer. This is a classic case where the candidate should trust their precise calculation rather than forcing a match with an incorrect option. 2) Why the incorrect options are incorrect: - Option D (12.5): This option is a distractor that arises from using the wrong metric. If you divide the GDP per capita (38,000) by the R&D investment (3,050) of France, or if you invert the logic and divide the investment by the number of patents, you might arrive at similar numbers. It is a metric selection error. - Option D (18.2): This option likely comes from calculating the ratio for the country with the second highest investment (France: 3,050 M € and 3,500 patents -> 3,500/3,050 ≈ 1.14, does not match directly, but could be a calculation error with Spain's GDP or a confusion with the R&D to GDP ratio of Sweden). It is a plausible calculation based on data from other countries, designed to confuse if the correct country is not identified. - Option D (24.8): This is the most dangerous trap. You might get it if the candidate rounds prematurely before dividing (e.g., 380,000 / 15,000 ≈ 25.3) or if you make a decimal point error in the division (e.g., 380,000 / 15,400 = 24.67, and rounding it incorrectly to 24.8). It is very close to the actual value, which leads to the temptation of marking it without verifying the precision. - Option D (31.4): This option results from inverting the ratio (Dividing investment by patents: 15,400 / 380 ≈ 40.5) or using data from Sweden (1,100 M € and 450 patents -> 450/1,1 ≈ 409, does not match, but could be a multiplication by 10 error). It is a fundamental logic division error. 3) Quick tip: In the EPSO, if your precise calculation does not match any of the numerical options exactly, verify immediately if there is a rounding error or if the correct answer is 'None of the above'. Do not force a calculation to match an incorrect option; precision is key.
