PUZZLE 7- From the 16th to the 22nd November (to be collected by the 23rd of November)

A FIERCE BATTLE
In a fierce battle, say that at least 70% of the soldiers have lost an eye; at least 75% an ear; at least 80% an arm; and at least 85% a leg.
What percentage, at least, must have lost all four? (Lewis Carroll)

SOLUTION:

At least 45% lost an eye and an ear (70+75 = 145)
At least 65% lost an arm and a leg ( 80 +85 = 165)
Therefore at least 10% lost an eye, an ear, an arm and a leg (45 + 65 = 110).
