40% of the inhabitants of a district having car, 15% of the remaining inhabitants moved to another district. The number of cars is then reduced to 8500. What is the number of original car owners?

Let the total number of original car owners be x.
Then, (100-40%) of (100-15)% of x = 8500
(60/100)(85/100)x = 8500
51/100x = 8500
x= (8500)(100)/(51) ~ 16666
