18 : 12 : ??

we start with the days:if the days increase the number of fans being made also increase so the solving ratiowill be an increasing one:12/7 ×560=960.Then we go to the no. of machines.......if the no. of machines decrease then no. of fans being made also decrease so the solving ratio is a decreasing one:18/20 × 960=864

answer:864fans
