Title: egg and a half
Post by Lynda Morris on Jul 7^th, 2005, 12:03pm

If a hen and a half lays an egg and a half in a day and a half ,how many eggs are laid by a dozen and a half laying better by half in a week and a half?
Please can you help solve this ?

If a hen and a half lays an egg and a half in a day and a half, then [hide]a hen lays an egg in a day and a half, so a hen lays 2/3 in a day[/hide]. So a dozen and a half, [hide]18 hens,[/hide] laying better by half, [hide]2/3 * 3/2 = 1 egg in a day,[/hide] in a week and a half, [hide]7 * 3/2 = 10.5 days,[/hide] lay [hide]18 * 1 * 10.5 = 189[/hide] eggs.

This is an old riddle :P

[hide]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*18) eggs a day. Since a week and a half is 10 and a half days, they lay 126 eggs.[/hide]
