While driving through the countryside one day I saw a farmer
tending his pigs and ducks in his yard. I was curious to know how many of each
he had. I stopped the car and inquired. Leaning on the stile jovially, he replied,
‘I have altogether 60 eyes and 86 feet between them’.
I drove off trying to calculate in my mind the exact number
of ducks and pigs he had.
What do you think is
the answer?
Answer: There were sixty eyes, so there must have
been thirty animals. Now the question is what combination of four- legged pigs
and two- legged ducks adding to thirty will give 86 feet. With some pencil
work, we get the answer 13 pigs and 17 ducks.
