guys can someone explain what this means "One of the poles was planted dipper than the other pole."

@mohan: in this question you really dont need to know mathematical stuff

All you need to know is the common sense that the larger the pole, the longer its shadow..

so for if 14 mt long pole casts a shadow of 10 mts,

x will cast a shadow of 8 mts

therefore x = 14 *8 /10

i actually di it that way but just wanted to know if there is some maths which i was missing

and whatever you have asked for,,

both the poles are of similar height but one pole is planted deeper means its height above the ground is decreased as it is burried deep in the ground when compared to the other pole which has the same height
