Question

an electric pole casts a shadow of lenght 20m at a time when a tree 6m high casts a shadow of lenght 8m.find the height of the pole.

Answer 1

Shadows of all the objects are proportional to their height.
Let the height of Electric pole be x m.
Therefore,
x/20 = 6/8
=> x = 6×20/8
=> x = 15
This x m = 15 m [Answer]
