Predictions Give You High Standards

Test 0 - Section 1 - Question 25

Logical Reasoning Difficulty: 4


Explanation


Okay, so: "unsalable" garments are 7 percent of garments produced, and all of those get scrapped. "Unsalable" only includes two sources of garments: those rejected by inspectors and those returned by retailers. But total scrapped garments account for 9 percent of garments produced. So, clearly, there must be another source of scrapped garments. (There could be some other explanation, but "any other source of scrapped garments" is my immediate first thought.)


Examples of "other sources of scrap" would be something like "moth infestation in a warehouse" or "forklift accident while loading the truck." These would be neither "found defective by inspectors" nor "returned by retailers." Instead it's folks in the warehouse all like "ah shit Herb, I done broke a water main and ruined an entire pallet of these totally cute rompers omg!"


We're asked to explain the discrepancy. Heading into the answers, I'm looking for any additional source of scrapped rompers.


A) This isn't an additional source of scrapped rompers.


B) Don't care. We already accounted for returns from retailers.


C) Don't care. We already accounted for inspector defects.


D) Don't care. We were talking about relative numbers. The total number produced isn't relevant. I'm hunting down a source of those 2% of additional scraps.


E) Oh wow. Definitely not what I predicted. But it's the answer nonetheless. If this is true, there actually aren't any additional ruined rompers. Instead, "unsalable" is measured by counting the rompers, which turns out to be 7% of rompers. But "scrap" is measured a different way! If scrap is measured by weight, and if scrap were heavier than average rompers. then this could be explained as "well, XXXL sizes tend to get returned more often," or "well, returns and defects tend to have stuff spilled on them, making them heavier."

Making a solid prediction helps you see how bad the bad answers are. E wasn't exactly what I predicted. But it gave me high standards, which helped me quickly reject A-D. The answer is E because it's the only one that explains how "scrap" could be 9% while "unsalable" is only 7%.
