A Problem of Wearing Shoes



      On a certain island, 5% of the 10000 inhabitants are one legged and half of the others go barefoot. What is the least number of shoes needed in the island?

Answer:   10,000 – Surprised? Well, this is how it works out. It is really immaterial what percentage of the population is one legged! In any case the one-legged people will all require on shoe per head. From the remaining, half will go barefoot and therefore they need no shoes and the rest will need two shoes per head. 

And this works out at one shoe per person for the ‘others’.

Therefore, we shall need for the whole population on the average one shoe per head.
