I want the variable to stand for the age of the youngest woman so that the ages of the other two will be the age of the youngest plus something. If I let the variable stand for the age of one of the other two then the age of the youngest will be that age minus something, and I would rather not have to deal with subtraction. Read the question. Kate is younger than Tess and Nina is older than Kate so Kate is the youngest. Thus I would start this way.
