Henry Ernest Dudeney/Modern Puzzles/79 - Egg Laying

by : $79$

 * Egg Laying
 * The following is a new variation of an old friend.
 * Though it looks rather complicated and difficult, it is absurdly easy if properly attacked.


 * If a hen and a half lays an egg and a half in a day and a half,
 * how many and a half who lay better by half will lay half a score and a half in a week and a half?
