floor(n/2) + 2

(n-1+floor(99/n)) is minimal for n=10. You drop the egg from the 10th floor, if it breaks, than you go one-by-one from the first floor -> 10 trials. If it does not break, you drop it from the 20th floor. If it breaks, you go from 11 to 19 -> total 11 trials. Worst case: you drop it from 10, 20, 30, 40, 50, 60, 70, 80, 90 (break), 81,82,83,84,85,86,87,88,89 -> 18 trials. (If it does not break on 90, you can go for 95, and have tha answer in 14 drops worst case). So tha answer is 18.

floor(n/2) + 1
