Back in the year 1936, people born in 1892 were able to make an unusual mathematical boast, a boast that people born in 1980 will be able to make at some time during the 21st century. John Stuart Mill, the English philosopher and economist, would also have been able to make the same boast, had he noticed it.
Given that he was born in the 19th century, can you tell me what the unusual boast was, what year he was born in, and what year he could make the boast in?
I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!

In 1936, people born in 1892 were 44, and 44*44=1936.ReplyDelete
In 2025, people born in 1980 will be 45, and 45*45=2025.
Mill must have been born in 1806, so that he would turn 43 in 1849, and 43*43=1849.
