## Bachet Weighing Problem

June 3rd, 2015 by Math Tricks | No Comments | Filed in Historical Math Puzzles

This puzzle goes ~~weigh~~ way back, several hundred years, and was devised by Claude Gaspard Bachet de Méziriac.

His puzzle does take some thought, and you have to be careful with the wording:

**What is the least number of weights that can be used on a scale pan to weigh any integral number of pounds from 1 to 40 inclusive, if the weights can be placed in either of the scale pans?**

Good luck!
