A flock of geese was flying in the sky, as suddenly one goose flew towards them. “Hello, a flock of hundred!” - he greeted them.
“We are not a hundred” - replied the leader of the flock. “If there were as many of us as is now, and plus again as many, and plus half as many, and plus quarter as many and even you, Goose, then we would be a hundred.”
How many geese were in the flock?
Explanations
36 geese.
36 (...as many of us as is now...) + 36 (...plus again as many...) + 18 (...plus half as many...) + 9 (...plus quarter as many...) + 1 (...and even you, Goose...) = 100
