A chicken farmer has figured out that a hen and a half can lay a egg and a half in a day and a half How many hens does the farmer need to produce one dozen eggs in six days?
Answer Three hens will lay 4 eggs each. Here's the logic: Hmm, 1.5 hens lay 1.5 eggs in 1.5 days doubled (to form usable whole numbers) is 3 hens laying… 3 eggs, in the same 1.5 days. 4 times the number of days (6) gives 4 X the number of eggs (3 eggs X 4 = 12 eggs) So, 3 hens taking 4 times as long (6 days) lay 12 eggs. Answer Take away the halves. 1 hen will lay one egg each day. Therefore, he needs 2 chickens. (MORE)
