Question

A tree 6m tall casts a 4m long shadow. At the same time, a flagpole casts a 50m long shadow. How long is the flagpole?

Answer 1

It's a direct variation question.

Let's solve,

In direct variation we do as follows-:

Let the height of the pole be x

6m=4m

x=50m

6/4=x/50. (cross multiply)

50*6=x*4

50*6/4=x

25*3=x

x=75

Means the flag pole height is of 75m.

Answer 2

75 is the correct answer
