There is a building of 100 floors
-If an egg drops from the Nth floor or above it will break.
-If it’s dropped from any floor below, it will not break.
You’re given 2 eggs.
Find N
How many drops you need to make?  Pick:
A) 14	B) 22	C) 18	D) 25 sec	E) 38
A   14   This follows the below logic.   Say, the egg breaks at floor n we try to find out by going (N-1) till the first floor by doing linear search.   Say for example, I throw the egg from 10th floor, and it breaks, I wíll go to floor 1 to 9 to find out the floor..   Then I would try the same logic for every 10 floors thereby setting a worst case scenario of 19 chances.. I.e. 10,20,30,40,50,60,70,80,90,100,91,92,93,94,95,96,97,98,99   To find optimum solution, let’s try this:   If for every n, egg doesnt break, instead of going to next n, go to N-1, this would save us one drop as we are doing a linear search with second egg when egg1 breaks…   So the series would look something like this..   N + (N-1) + (N-2) + (N-3) +…+ 1   Now this is a series which is equal to N(N+1)/2   Now since it is given that the egg may or may not break from 100th floor..   We can write it as..   N(N+1)/2&gt;=100   And n=14(approx)   So we should start from 14 then move up N-1 to 13 floor I.e. 27,39…   So the floors from where the drop needs to be done are: 14,27,39,50,60,69,77,84,90,95,99,100   So the answer is 14
