What we know: On return from the battlefield, the regiment is badly battle-scarred. 70% of the soldiers lost an eye, 75% lost an ear, 85% lost an leg, and 80% lost an arm.
Enigma: What percentage has all four wounds?
Solution: Add the percents to get 310 out of 100 soldiers. This gives 3 injuries to each and 10 with 4. The last percentage is 10%
