OVER THE TOP OF A FENCE IS PLACED A ROPE. THE SAME
AMOUNT ON EACH SIDE. THE ROPE WEIGHS 1/3 LB. PER FOOT.
ON MY END OF THE ROPE HANGS A MONKEY HOLDING A
BANANA AND ON THE OTHER END IS A WEIGHT EQUAL IN WEIGHT
TO THE WEIGHT OF THE MONKEY.
THE BANANA WEIGHS 2 OZ. PER INCH. THE LENGTH OF THE
ROPE (IN FEET) IS EQUAL TO THE AGE OF THE MONKEY, AND
THE WEIGHT OF THE MONKEY (IN OZS.) IS AS MUCH AS THE AGE
OF THE MONKEY'S MOTHER. THE COMBINED AGE OF THE MONKEY
AND ITS MOTHER ARE 30 YEARS.
THE WEIGHT OF THE BANANA PLUS 1/2 OF THE WEIGHT OF THE
MONKEY IS 1/4 AS MUCH AS THE SUM OF THE WEIGHTS OF THE
WEIGHT AND THE ROPE, WHERE ALL WEIGHTS ARE IN THE SAME
UNITS.
THE MONKEY'S MOTHER IS 1/2 AS OLD AS THE MONKEY WILL BE
WHEN IT IS THREE TIMES AS OLD AS ITS MOTHER WAS WHEN
SHE WAS 1/2 AS OLD AS THE MONKEY WILL BE WHEN IT IS
TWICE AS OLD AS IT IS NOW.
QUESTION: HOW LONG IS THE BANANA?
