Question

a vertical stick 1.2 M long cast a shadow of 40 cm long on the ground at the same time a pole 6M high cast a shadow x on the ground find the value of x

Answer 1

Length of shadow casted by 1.2m long stick= 40cm
Length of shadow casted by 1m long stick= 40/1.2
=400/12
Length of shadow casted by 6m long stick=400/12×6
400/2
200cm
2m

Answer 2

Here, you coupd also apply BPT i.e. Basic Proportionality Theorem

Therefore, 1.2/6 = 40/x
x = 40*5 = 200 cm
x = 2m
