einstein's riddle

OMG! OMG! I'm one of those in the top 2% of the world's most intelligent population who can solve Albert Einstein's riddle!!! Super smart me!!!

Albert Einstein had supposedly written the below riddle during the 19th century (according to several sources, although dunno how true) and claimed that 98% of the world population would not be able to solve it. I tried and took about 40min to come up with an answer. And it's correct! Hey Hey try it out!

There are no tricks, just pure logic, (can just Google anytime to find out the right answer, but then it won't be challenging if you cheat) so GOOD LUCK!
