Turn on one light bulb and leave it on for a while. Turn it off\nTurn on a second light bulb and leave it on. Go up stairs.\nThe second switch obviously turns on the bulb that is on.\nThe first switch (you turned on then off) is for the lightbulb that is NOT ON but is warm from being used. \nThe  3rd switch obviously is the one for the unlit lightbulb that's cold.

This is more of a word problem or a riddle than a math problem.\n\nThe answer is 7 (SEVEN).  Remove its first letter and it becomes EVEN!

Great puzzle, took me awhile to make it to f=1, g=4. The letters are from a-i: 9,8,7,2,6,1,4,5,3.\n\nPlugged in this is: (9 * 87 + 2/6) / (14 + 5/3) or (783 + 1/3) / (15 + 2/3) which equals 50.\n\nAnswer logged Sunday, March 12th, 3:20 pm with no other valid answers yet. Sorry to have to write that, but I've seen people change their answers too many times in the past.

The correct answer is "NO"... (That's why kindergarten students can answer it.)\n\nThe last line of the riddle should read, "Can you guess the correct answer?"
