How many eggs would six hens lay at the same rate in six days? [Ref: ZPZF] Copyrighted Direct Link: www.brainbashers.com?ZPZF Hint: Think about three hens first. Answer: 24. We are told that:    1.5 hens will lay 1.5 eggs in 1.5 days. We can double the chickens (which doubles the eggs):    3 hens will lay 3 eggs in 1.5 days. We can double the chickens again:    6 hens will lay 6 eggs in 1.5 days. We can now multiply the number of days by 4 (which multiplies the number of eggs by 4).    Therefore 6 hens will lay 24 eggs in a 6 days.
