Blog Post #44: MG

Dear Readers,

The car pictured below is a stunningly beautiful MG-B Roadster, but I honestly find today’s original math brainteaser to be equally appealing, and you’ll certainly deserve the title of ‘MG’ for Mathematical Genius when you enjoy pondering and cracking this brainteaser!! It goes as follows…

In some future year, the reciprocal of Martin’s age on his birthday in the future year plus the reciprocal of the 20th century year in which Martin was born will equal 1/44, the reciprocal of 44. Your brainteaser is to figure out Martin’s birth year. A solution will be given in Blog Post #45.
