Answer is 0.5% bcoz...take n=100?then?memory m=sqrt(100n)=sqrt(10000)=100Increase n by 1% thenn=101?then memory m=sqrt(100n)=sqrt(10100)=100.5then memory will be increased by 0.5%

No. of cats = x(say)
Therefore, no. of mice killed by each cat = 999919/x (since, they killed equal no. of mice)
Now, given that
(999919/x) is greater than x, i.e
999919/x > x, implies x*x<999919
Therefore, x < 999.95(approx). Now, the only no. which is nearest to but less than 999.95 and is a factor of 999919 is 991.
Thus, x = 991 and no. of mice = 999919/991 = 1009.amith.aec

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)(9...
