Two poles cast shadow 12 m and 14 m respectively. If height of one is 48 m, what can be possible height of second?
- A. 56 m ✓
- B. 62 m
- C. 50 m
- D. 45 m
Correct Answer: A. 56 m
Explanation
The ratio of heights to shadows is constant at the same time of day. \frac{h_1}{s_1} = \frac{h_2}{s_2} \Rightarrow \frac{48}{12} = \frac{h_2}{14} \Rightarrow 4 = \frac{h_2}{14} \Rightarrow h_2 = 56 m.
