Romulus and Remus, are identical twins, or are they?

If you would like to visit the two brothers, have a close look at their pictures and decide how many differences you can see. When you are happy that you have “spotted” the difference, you can find the missing values for the North co-ordinates. Simply multiply the number of differences by ninety-four and add three.
For North N53º 16.XXX
To find the West co-ordinates multiply the number of differences by thirty-seven and add four
For West W003º 03.XXX
Please remember your eyes may play tricks on you, and it is not uncommon for gnomes to be mischievous too! Please, therefore, check very carefully the co-ordinates that you have worked out before you go in search of the brothers.
Because there is no geo-checker on the page, the Wirral Gnome Society takes no responsibility for where you may end up. If in doubt about your answer contact the Wirral Gnome Society or one of its many members to check your solution.
Have a happy day!
