How to solve puzzles?

First you read carefully the statement in the introduction, then draw a chart that takes into account every possibility to be considered in the solution. Next you enter in the chart all the information immediately apparent from the clues, using an ' x ' to show a definite 'no', and ' ✓ ', for example, to show a definite 'yes'. You will find that this narrows down the possibilities, and might even reveal some new definite information. So now, you re-read the clues with these new facts in mind to discover further positive/ negative relationships. Besure to enter one '✓ ' in each row or column of possibilities.
