If a continuous cable 10 meters long was marked off at intervals of 1/3 meter and also 1/5 meter, and then if the cable were cut at each mark, how many different size length of cable would result?	Choose the correct choice from the following:
A) 1  B) 2  C) 3  D) 4  E) 5
In this particular example length (10 meter) is just extraneous information.   The location of the marks for 1/3 meter would be 5/15, 10/15, 15/15, etc...   The location of the marks for 1/5 meter would be 3/15, 6/15, 9/15, 12/15, 15/15, etc...   The distances between marks are 3/15, 2/15, and 1/15.   The answer is 3.
