Question 72

The Qutab Minar casts a shadow 150 m long at the same time when the Vikas Minar casts a shadow 120 m long on the ground. If the height of the Vikas Minar is 80 m, find the height of the Qutab Minar.

Solution

The triangles formed by Qutub and Vikas minar will be similar, so

Let x be the height of the Qutub minar

150/120 = x/80

On solving, we get

x = 100 m
