This query is for SQL Server, but if you change the escaping characters [] you can run it on every database.
Basically you JOIN
all tables with the relevant columns ang GROUP BY
montn and geography
SELECT ta.[geographies],tb.[month], SUM([Sales]) total_amount FROM TableA ta JOIN TableB tb ON ta.[geographies] = tb.[geographies] JOIN TableC tc ON tc.[Stores] = tb.[Stores] AND tb.[month] = tc.[months] GROUP BY ta.[geographies],tb.[month]
geographies | month | total_amount:---------- | ----: | -----------: Atlanta | 1 | 125 Atlanta | 2 | 50 Miami | 1 | 35
