A question, every week.

For twelve years Sreenivasa set ten questions an issue in the Sanghamitra magazine and printed the winners in the next one. The habit is back, one question at a time.

A hall of people working on a puzzle together at Mathemagics 2014, Fairfax, Virginia
Mathemagics 2014, City of Fairfax Regional Library, Virginia — the audience solving a puzzle. The questions have always been asked out loud first.

How it works

These were his rules from 18 April 2015, when the Srinivasa Ramanujan Mathematricks Club put up one question every week, and they still are.

  1. The first five correct answers score, in order: 5, 4, 3, 2 and 1 points.
  2. Whoever reaches 25 points first wins that cycle.
  3. Answers go to Sreenivasa directly. He keeps the score.

A weekly question from 2016

The club put up one question every week. This is Question 130, from 13 February 2016.
