So a dozen and a half, 18 hens, laying better by half, 2/3 * 3/2 = 1 egg in a day, in a week and a half, 7 * 3/2 = 10.5 days, lay 18 * 1 * 10.5 = 189 eggs.   --SMQ IP Logged --SMQ raprap Newbie     Gender: Posts: 23 Re: Math problem?   « Reply #2 on: Jul 7th, 2005, 12:45pm » Quote Modify This is an old riddle http://www.straightdope.com/classics/a3_187.html   An hen and a half laying an egg and a half in a day and a half is the same as one hen laying one egg in a day and a half, or One hen lays 2/3 of an egg in a day.   so 18 hens lay 12 (2/3*1 eggs a day.  Since a week and a half is 10 and a half days, they lay 126 eggs.   Rap IP Logged Lynda Morris Guest Re: Math problem?   « Reply #3 on: Jul 7th, 2005, 3:31pm » Quote Modify Remove Thank you for your promt replies.
