The kitchen took 4 * .5 = 2 hours longer than the bedrooms. So the kitchen took 4 + 2 = 6 hours. The bedrooms took 3 * 4 = 12 hours. So the kitchen and bedrooms combined took 12 + 6 = 18 hours. The living room took 18 * 2 = 36 hours. So everything took a total of 18 + 36 = 54 hours.is the reasoning for what question and answer pair?
