Yet another time, a fine question has been disturbed. The real question, in its orignal form is,

"If a chicken and a half can lay an egg and a half in a minute and a half, how long will it take a wooden-legged cricket to kick all the seeds out of a dill pickle?"

Follow the logic of this original and apply it to your problem.

If 1 1/2 chickens lay 1 1/2 eggs in 1 1/2 days, how many chickens will be required to lay 20 eggs in 6 days?

Chickens...Eggs...Days
....1 1/2......1 1/2...1 1/2
.......3............3......1 1/2
.......3............6.........3
.............Therefore
.......3...........2..........1 and
.......1..........2/3........1
.......1...........4..........6 and
.......5..........20.........6

Alternatively

Each chicken will lay one egg in 1 1/2 days

In 6 days [ 4 times 1 1/2 ]

Each chicken will lay 4 eggs in 6 days

Therefore, 5 chickens will lay 20 eggs in 6 days.
