Question

A 4m tall flag post cast a shadow of 6m. At the same instance a Building casts a shadow of length 24m. what is the height of the building

Answer 1

a 4m tall flag cast a shadow = 6m
so a 1m tall flag cast a shadow = 6\4
building cast a shadow of length = 24 ×6/4
answer 36metre

Answer 2

it would be 16 as on 4m it cast a height of 6m & when we divide 24 by 6 we get 4 & when we subtract height of flag post from cast height of it we get 2 so we multiply 4&2 , we get 8m & when we subtract it from 24m we get 16m answer
