One and a Half Hens Puzzle - Solution
The Puzzle:
If one and a half hens lay one and a half eggs in one and a half days, how many eggs does one hen lay in one day?
Our Solution:
Find the daily rate per hen:
Hens × Days × (Daily Rate) = Eggs
1½ × 1½ × (Daily Rate) = 1½
(Daily Rate) = 1½ / (1½ × 1½)
Daily Rate = 1/(1½) = 2/3
So 1 hen in 1 day will lay two-thirds of an egg
Hens × Days × (Daily Rate) = Eggs
1½ × 1½ × (Daily Rate) = 1½
(Daily Rate) = 1½ / (1½ × 1½)
Daily Rate = 1/(1½) = 2/3
So 1 hen in 1 day will lay two-thirds of an egg
