    If we start dropping the egg from 1st floor and try till 100 till the egg doesn’t break .We will require 100 eggs in worst case. Lets try to drop the egg from every 2nd floor .This will require 51 drops in worst case .Here’s how (100/2)=50 , let’s say the egg broke on 100 the floor now drop it from 99th floor it should not break. Similarly for dropping from every 3rd floor gives 35 drops [100/3 +3-1].Let’s say minimum number of steps required when we drops egg from every xth floor.

    There fore minimum drops required would be [(100/10)+10-1]=19
