A vertical stick 12 cm long casts a shadow 8 cm long on the ground. At the same time, a tower casts a shadow 40 m long on the ground. The height of the tower is
The proportions of the length of the shadow and the height of the tower are constant.
Let the height of the tower be 'h'
Hence, $$\frac{h}{40}=\frac{12}{8}$$
So, $$h=60$$
