How can I use multiple field separators or multiple awk to process columns
<p>I have a tab separated file which looks like the following</p>

<pre><code>John  1,0   3,2   5,6
Mike  3,2    4,5   0,0
James 3,0    5,3   4,5
</code></pre>

<p>I would like to add all the first elements of 3 fields and add second elements of 3 fields output the following</p>

<pre><code>John 9,8
Mike 9,7
James 12,8 
</code></pre>

<p>Is there is a solution in awk where I can use multiple field separators?</p>
