A tree is 12 m tall and casts an 8 m long shadow. At the same time, a flag pole casts a 100 m long shadow. How long is the flag pole?

A) 150 m

B) 200 m

C) 125 m

D) 115 m

Correct answer:
A) 150 m

Description for Correct answer:
Because, 8 m shadow means original height = 12 m.

Therefore, 1 m shadow means original height = \( \Large \frac{12}{8} \) m

Therefore, 100 m shadow means original height

= \( \Large \frac{12}{8} \) *100m = \( \Large \frac{6}{4} \times 100 \)

= \( \Large 6 \times 25 \) = 150 m
