Was leafing through the stack of pending puzzles, and came across this cool math brain teaser I totally forgot to put up last year. It was created by math whiz MichaelC. Haven’t seen him around in awhile, hope he’s doing ok.
“I know the birth years of myself, my mother, and my sister are prime numbers. And I know when my mother celebrates her birthday this year, the sum of our ages will be 196 years. I also know my sister is 2 years older than I am.
But the question I have is, how old is my mother?”
