Hi there!

I have a logic question attached. it reads in swedish " Find the route from the red to the green dot so that the sum of the numbers is equal to 400."

The way I see it there's no fast way to solve this problem. You simply have to try each route until you blindly make it to the correct one? Is this question just busy work or can one use a reliable method to narrow down the possible routes one can use to arrive at the sum of 400?

So basically what I would like to know is if there's anyone out there who can give me the fastest and quickest way of methodically solving logic problems like this one; Any help here?

Thanks!
