an appliance shop orders 24 boxes of small electric fans ( where all boxes contain the same number of small fans) and 25 boxes of bigger electric fans ( where all boxes also contain the same number of bì fans). The total number of fans ordered is 1200. How many fans are there in each box that contains small fans
