You have a five cup mug, a three cup mug, a water supply, a sink with a drain, and a packet of instant coffee which when dissolved in one cup of water produces coffee of strength 100%.

The packet may be used at any time, but the entire contents of the packet must be dissolved into a single mug when it is used.

Your task is to fix 4 cups of coffee at exactly 16% strength.

Uggh, why would you do that to my coffee.
I was working to make 16.67%, whoops.
