You have two coconuts and you want to find out how high they can be dropped from a 100 story building before they break. But you only have $1.50 and the elevator costs a dime each time you ride it.

How can you drop the coconuts to guarantee you will find the lowest floor they will break at, while starting and ending at floor 1?

Note: They break when dropped from the same height and they don't weaken from getting dropped.

So here's my crack at it.
Take coconut 1.
Start at floor one then go upwards stopping at regular intervals, say 10, 20, 30 and so on.
Whatever one that coconut breaks at, say 50, go to the floor above the previous interval so in this made up example it'd be 41.
Then drop the second coconut here, and keep going up till it breaks.

Simples, no?

You were very close. Here's the real answer:

You could drop it at floor 1 first (because you start at floor 1). Then you would go to the floors: 14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, and 100. Whatever floor your first coconut breaks at, go to the floor above the last floor the coconut survived and drop the second coconut from this floor. Then go up by one floor until the second coconut breaks and that is the lowest floor it will break at.

Now here's our new riddle for the day:

My first is often at the front door.
My second is found in the cereal family.
My third is what most people want.
My whole is one of the United States.

What am I?

Close, but no cigar. BTW, Ark, would you mind updating Turalyon 514's recruitment thread? I would do it myself but you were the original author for it. Anyway, I'll give everyone one last chance to answer my previous riddle, then we'll move on. Join Turalyon 514 today! Click here for more info.

Mat=Door mat, at a front door. Ri=rye, which is a cereal. Money=Who doesn't want it? And the word itself is a state in which 2 people are united. That took far too long to figure out.
