A flagpole 18 meters high casts a shadow of length 45 meters. If a building under similar conditions casts a shadow of length 50 meters, what is the height of the building (in meters)?  Choose the correct choice:
A) 16
B) 20
C) 24
D) 28
E) 32
The height:length ratio will be equal in both cases.   18 / 45 = x / 50   x = 20   The answer is 20.
