Quantitative Aptitude (CDS) Percentage

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?

16666

14567

17956

11200

Explanation:

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
