Hi,

A rope lying over the top of a fence is the same length on each side; it weighs one third of a pound per foot. On one end, hangs a monkey holding a banana; on the other end, hangs a weight equal to the weight of the monkey. The banana weighs two ounces per inch. The rope is as long (in feet) as the monkey is old (in years). The weight of the monkey (in ounces) is the same as the age of the monkey's mother (in years). The combined age of the monkey and it's mother is thirty years. One half the weight of the monkey, plus the weight of the banana, is one fourth as much as the weight of the weight and the weight of the rope. The monkey's mother is half as old as the monkey will be when it is three times as old as it's mother was when she was half as old as the monkey will be when it is as old as its mother will be when she is four times as old as the monkey was when it is twice as old as it's mother was when she was three times as old as the monkey was when it was one fourth as old as it is now. How long is the banana?

Any help will be apprecited.

I didn't find the right solution from the Internet.
