The floors are polished on Monday and two other non-consecutive days. Since plants are watered on two non-consecutive days, the only valid combination of days for floor polishing, while adhering to these conditions, is Wednesday and Thursday
According to the schedule, plants are watered on two non-consecutive days. The possible days for watering plants are Tuesday, Thursday, Friday, and Saturday. Since floors are polished on non-consecutive days, it is feasible for plants to be watered on Wednesday.
If dinner is served on a day that plants are watered, then based on the schedule, that day cannot coincide with the floor polishing day. Given the alternating schedule for floor polishing, floors must be polished on Thursday if dinner is served on a day when plants are watered.
If floors are polished on consecutive days, then it is possible to determine exactly which days both plants are watered and floors are polished, as the schedule is clearer. Thus, it is possible to determine this for all six days of the week.
