A flock of geese is flying while another goose is flying past it. The goose asks the leader of the flock how many they are. The leader answers:
"Us, plus us, plus half of us, plus a quarter of us, plus myself make the flock 100 geese. How many are we?

Let "us"=a
a + a + a/2 +a/4 + 1 = 100
a + a + a/2 +a/4 = 99
2a + a/2 +a/4 = 99
a (2 + 0.5 + 0.25) = 99
a (2.75) = 99
a = 36
a + a + a/2 +a/4 + 1 = 100
a + a + a/2 +a/4 = 99
2a + a/2 +a/4 = 99
a (2 + 0.5 + 0.25) = 99
a (2.75) = 99
a = 36
