Question

Riddle 4 da kidz =]

There are 100 floors, and you have 2 coconuts, you have to find the lowest floor the coconut breaks, it costs $0.10 to ride up the elevator, but its free to ride down, and you have $1.40. How will you find the lowest floor the coconut breaks at ?

Answer 1

would it be the 5 floor

Answer 2

ok, so the finances allow 14 chances to go upwards

this is how i would go
1) go to the 15th floor and chuck 1 coconut
if break, come all the way down and start going up the floors one by one

2) if not broken in 15th, i still have 13 more chances to go upwards, so now go to the 29th floor and chuck, if broke, go back down to the 15th floor and test each floor till i reach the 28th floor

continuing the logic

floor chances left
15 13
29 12
42 11
44 10
55 9
65 8
74 7
81 6
88 5
94 4
98 3
