Answer» OBSERVING the num 999919 which is the total num of rats being EATEN, we can WRITE it as (1000000-81) = (1000^2-9^2) = (1000+9)(1000-9) = (1009)(991) So total num of rats killed =(1009)(991) And GIVEN that each cat kills more num of rats than the total num of cats Hence each cat kills 1009 num of rats And there are 991 num of cats Observing the num 999919 which is the total num of rats being eaten, we can write it as (1000000-81) = (1000^2-9^2) = (1000+9)(1000-9) = (1009)(991) So total num of rats killed =(1009)(991) And given that each cat kills more num of rats than the total num of cats Hence each cat kills 1009 num of rats And there are 991 num of cats |
