The question was about a temperature sign where a driver noticed the digits were exactly reversed, comparing deg C vs deg F. 28/82 & 16/61 (C/F) were the two answers.
But those numbers are actually rounded to the nearest integer. 28 C = 82.4, and 16 C = 60.8.
Here’s an extended version of this puzzler: Are there any combinations in integer pairs that are exact matches? So only pairs that are exact integers are allowed,. 0 and 32 are an exact integer pair, as well as 100 and 212. There’s many others. From that list, are there any where the pair match up when reversed? I don’t think there are any solutions for positive 2 digit integers. Do you agree? If so, what about negative 2 digit integers? I don’t think there are any of those that work either. So what about 3 digit integer pairs? Any exact integer solutions this puzzler? If so , what’s the one w/the fewest digits.? Or is there even one at all?
I don’t know, just asking.
