A teenage boy smitten with a teenage girl in his high school freshman class makes his feelings known. Overjoyed at finding them reciprocated, he took a pen knife to a young hardwood tree in the vicinity and carved their initials within a heart five feet up on the tree’s trunk, as boys will do. They go back 28 years later. If the tree had added 35% to its height in the first fifteen years of his absence, 10% in the following five years, and two and a half percent in each of the ensuing eight years, how far up the trunk did they have to look to find the carving with their initials?

5′

Nope, not even close. Try again.

Whacha talkin about Willis? A tree grows from the tips of each branch and not from the ground, so the initials would still be 5′ above the base, exactly the same height as twenty-eight years earlier.

5 feet up.

Maybe a bit stecthed though…

Yes Julie, you are correct. My mistake on your first answer. Your second attempt explained it nicely. They will be at exactly the same height, which was in fact 5 feet.

You are today’s winner!

I’m glad Julie figured it out, I was stumped, no pun intended lol. So heres another wood riddle I found that you might want to add: Wacky Wood
