The length of the shadow of a tree of height 2.6 m is 6.5 m. At the same time, the length of the shadow of a building 20.2 m high is:
Answer & explanation
Correct answer: option 4
The given ratio of height and length:
⇒ Tree : Shadow = 2.6 : 6.5 = 2 : 5
*At the same time the above ratio remains same*
Therefore, ratio of height and length:
⇒ Building : Shadow = 2 : 5
Here,
⇒ 2R = 20.2
⇒ Length of shadow = 5R = \(\frac{20.2}{2}\) × 5 = 50.5 m
