The Puzzling Page
Barry R Clarke
Professor Neuron’s nephew Trifle was proud to have his first mathematical puzzle published in Perplex magazine. However, when asked by the professor what page number it was on he couldn’t remember.
“All I can recall,” said Trifle, “is that it’s a twodigit number, neither digit being zero, and less than ten pages before the middle of the magazine.”
