[ 20 ] Find the sum of the ages of everyone who wrote a problem for this year’s HMMT November contest. If your answer is X and the actual value is Y , your score will be max(0 , 20 − | X − Y | ) Proposed by: Allen Liu Answer: 258 There was one problem for which I could not determine author information, so I set the author as one of the problem czars at random. Then, I ran the following command on a folder containing TeX solutions files to all four contests: evan@ArchMega ~/Downloads/November $ grep --no-filename "Proposed by: " *.tex | sort | uniq -c 15 {\em Proposed by: Allen Liu } 1 {\em Proposed by: Brice Huang } 2 {\em Proposed by: Christopher Shao } 2 {\em Proposed by: Daniel Qu } 21 {\em Proposed by: Eshaan Nichani } 3 {\em Proposed by: Evan Chen } 9 {\em Proposed by: Henrik Boecken } 2 {\em Proposed by: Kevin Sun } 2 {\em Proposed by: Kevin Yang } 1 {\em Proposed by: Meghal Gupta } 1 {\em Proposed by: Rachel Zhang } 1 {\em Proposed by: Sam Korsky } 3 {\em Proposed by: Saranesh Prembabu } 3 {\em Proposed by: Shyam Narayanan } This gave the counts of problem proposals; there were 14 distinct authors of problems for November
Summing their ages (concealed for privacy) gives 258.
