A number of cats got together and decided to kill between them 999919 mice. Every cat killed an equal number of mice. Each cat killed more mice than there were cats. How many cats do you think there were?  Choose the correct choice
A) 1009
B) 1110
C) 1111
D) 1112
E) 1122
999919 = 1000000 - 81 = 1000^2 - 9^2 = (1000+9)(1000-9) = 1009*991.   Since there were more mice than there were cats, 991 cats killed 1009 mice each.   1009NSWER:1009
