Two Eggs puzzles
You are given 2 eggs.And there’s 100 floor building. Eggs can be very hard or very fragile means it may break if dropped from the first floor or may not even break if dropped from 100th floor.Both eggs are identical.You have to find the highest floor from which the egg can be dropped without breaking.What is the minimum number drops you need to make. You are allowed to break 2 eggs in the process.
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
