One day a duck flew over a lake on which a number of ducks were swimming. The duck in the air said, "Good morning, you hundred ugly duckings!"

One of the ducks on the lake answered: "We were not a hundred. We would need to add you to us plus the same number of us, half of us and a quarter of us. Then there would be a hundred, you stupid ducking"

How many ducks are there on the lake?

i think its 56?
