    When the tower casts a shadow of 40 m, same time what will be the length of the shadow of Vijay's house?

    A) 15m

    B) 32m

    C) 16m

    D) 8m

    Correct Answer: D

    Solution :

    Given, AC = 40 cm Let length of the shadow of Vijay's house be AB = l m Since,       \[\Delta ABE\tilde{\ }ACD\] \[\therefore \,\,\,\,\,\,\,\frac{AB}{AC}=\frac{EB}{CD}\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\frac{l}{40}=\frac{20}{100}\] \[\Rightarrow \,\,\,h=\frac{20\times 40}{100}=8\,m\]
