Here is a new great puzzle my coworker shared with me. By the way, he is in a delivery room right now waiting for his twin boys to emerge. All the best, Jonathan!
In a faraway land, the Queen's Army consists of 3 Corps.
Each Corp is composed of 3 Divisions.
Each Division of 3 Brigades.
Each Brigade of 3 Regiments.
Each Regiment of 3 Companies.
And finally each Company of 3 Soldiers.
Soldiers are either Air Force soldiers or Marines.Now, the rules, from the bottom of the hierarchy to the top:
Each Company is composed of either:
2 Air Force soldiers and 1 Marine (in which case it is named The Air Force Company)
2 Marines and 1 Air Force soldier (in which case it is named The Marines Company)
Each Regiment is composed of either:
2 Air Force Companies and 1 Marine Company (in which case it is named The Air Force Regiment)
2 Marine Companies and 1 Air Force Company (in which case it is named The Marines Regiment)
and so on till:
Each Army is composed of either:
2 Air Force Corps and 1 Marines Corp (in which case it is named The Air Force Army)
2 Marines Corps and 1 Air Force Corp (in which case it is named The Marines Army)
At the present time the Queen's Army is Marines Army. However Queen's new lover is an Air Force pilot and he convinced the Queen to change the Army to the Air Force Army. The question is: what is the minimum number of soldiers that the Queen needs to change so that her Army will become The Air Force Army?
