a data from gmat forum

by diebeatsthegmat » Wed Sep 21, 2011 8:24 pm
Two giant identical poles have been planted in the ground. One of the
poles was planted deeper than the other pole. The shadow of pole A is 10
meters long and the shadow of pole B is 8 meters long. How tall is pole
B?
(1) Pole A is hoisted 14 meters in the air.
(2) Pole B is located 2 meters from pole A

why is it A?

This question is bit unclear.

Using statement 1 we will be able to find the height of Pole A visible above the ground.

We cannot find anything about the pole inside the ground.

using statement 2: - is also of little help.

what is the source of this question?

I agree, the question is not clear enough, the question does not clearly say on which side of Pole A is Pole B.
