My uncle gave him an interesting practical question. There are two garment factories in Tian Quan Village, which produce coats and trousers with uniform specifications. Monthly use of a factory 16 (calculated by 30 days) As can be seen from the above, a factory can produce tops =448/ 16=28 pairs of trousers =448/ 14=32 pairs every day.

The factory can produce tops =720/ 12=60 pants =720/ 18=40 every day.

After the merger of the two factories, it can produce 28+60=88 tops and 32+40=72 pants every day.

Assuming that it takes X days to produce tops every month after the merger, it takes 30-X days to produce pants, including:

You can get 88X = 72(30-X):X = 13.5.

Then 88x13.5 =1188 sets can be produced every month.
