Question

An electric pole casts a shadow of length 20 metres at a time when a tree 6 metres high casts a shadow of length 8 metres, Find the height of the pole.​

Answer 1

Answer:

Let the height of the pole = x m

Then, we have :

x : 20 :: 6 : 8

Now, we know :

Product of extremes = Product of means

8x = 20 × 6

x = 120 / 8 = 15

Hence, the height of the pole is 15 m.
