I can do one of these questions in 2 minutes flat with my method:

1) Draw the Triangle
2) Place your starting currency at the lower left point (most likely USD)
3) Place the other two currencies at the other points
4) Go around the triangle converting your starting currency into the other two currencies and back into the home currency AT THE WORST RATE (if given the Bid/Ask just use the rate that gives you less of the converted currency)
5) If you get a negative value then go the other way around the triangle

Booom goes the dynamite

Hasn't failed me once.
