The "I Love You" TreeTrick brain teasers appear difficult at first, but they have a trick that makes them really easy.
When Mike and Milly were first going out, they carved their initials inside a heart on a tree trunk 3 feet off the ground. Exactly one year later, they married. The tree had grown 8 inches over the last year. During the following years it doubled its growth rate annually. How high was the heart on their tenth anniversary?
Answer3 feet. Trees grow from the top, not the base (trunk)!
