[Economics] CFAI - Reading 19 - Q: 4 & 5

What is the best/quickest way to figure out the arbitrage profit? I always have trouble with the start. I can figure out the rest easily, but I basically just guess and check and it’s extremely time consuming because you have to go through the entire process. How do you know that the way to make an arbitrage profit is to start off by borrowing 1,000,000 USD or by borrowing a million USD worth in Yen?

You will have to use the search function as this topic has been discussed many times. Just to make life little easy on you I found one such thread: http://www.analystforum.com/phorums/read.php?12,1121285

Awesome. Thanks!
