“Monkey and Pulley”: Solution
Solution to Monkey and Pulley, from Thursday:
We find the age of the monkey works out at 1.5 years, and the age of the mother 2.5 years, and the monkey therefore weighing 2.5 lbs., and the weight the same. Then we soon discover that the rope weighed 1.25 lbs., or 20 oz.; and, as a foot weighed 4 oz., the length of the rope was 5 feet.
(From Henry Dudeney.)
