ABSTRACT
This article presents a intelligence testing question. According to the question there are nine balls all look the same. One is slightly heavier than the rest, but the weight difference is not detectable except by weighing them. It is to be determined which is the heavy ball. In the last issue of the journal a question was asked related to a vertical wheel of 10cm radius. It was asked that what is the total number of rotations the smaller wheel makes when its centre makes one complete rotation about the larger wheel?. Solution to this problem has been provided in the article.
