StayWell marketing team considers sending small gifts to all residents and owners. To decrease the postal costs, they will send gifts to owners in batches to their corresponding offices. Similarly, the marketing team will send the gifts in groups to the residents living in the same property. Therefore, you will need to provide them the number of gifts for each StayWell office and number of gifts for each property. The column headers for the first table should be OFFICE_NUM and GIFTS, the column headers for the second table should be PROPERTY_ID and GIFTS.

 office and owner information are both available at PROPERTY table; however, it is possible for owners to have multiple properties. You only need to count DISTINCT owners in the database for sending gifts.
