At a particular time, the length of the shadow of Qutub Minar whose height is 72 m is 80 m. What will be the height of an electric pole, the length of whose shadow at the same time is 1000 cm?
∵Length of Qutub Minar = 72m
Its shadow at particular time = 80m
Length of shadow of electric pole = 1000cm = 10m
∴ Length of electric pole = 
82
