Heavily wounded (Posted on 2017-05-08)

In a group of soldiers,
if 70% have lost an eye,
75% an ear,
80% an arm,
85% a leg,

what percentage, at least, must have lost all four?

Ten. “Adding the wounds together, we get 70 + 75 + 80 + 85 = 310, among 100 men; which gives 3 to each, and 4 to 10 men. Therefore the least percentage is 10.
