auto selection of a radio button on selection of radio button from another set
<p>there is this set of radio buttons</p>

<pre><code>&lt;div class="wrapper"&gt; &lt;strong&gt; Number of images:&lt;/strong&gt;
&lt;div class="formText"&gt;
    &lt;input type="radio" name="rdNumber" value="100" /&gt;100
    &lt;input type="radio" name="rdNumber" value="200" /&gt;200
    &lt;input type="radio" name="rdNumber" value="300" /&gt;300
    &lt;input type="radio" name="rdNumber" value="400" /&gt;400
    &lt;input type="radio" name="rdNumber" value="500" /&gt;500
    &lt;input type="radio" name="rdNumber" value="600" /&gt;600
    &lt;input type="radio" name="rdNumber" value="1000" checked="checked"
    /&gt;1000
    &lt;input type="radio" name="rdNumber" value="1200" /&gt;1200
    &lt;input type="radio" name="rdNumber" value="1500" /&gt;1500
    &lt;input type="radio" name="rdNumber" value="1600" /&gt;1600
    &lt;input type="radio" name="rdNumber" value="other" /&gt;other
&lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>And there is this set of radio buttons</p>

<pre><code>&lt;div class="wrapper"&gt; &lt;strong&gt;&lt;span&gt;*&lt;/span&gt; Number of additional pages:&lt;/strong&gt;

&lt;div class="formText"&gt;
    &lt;input type="radio" name="rdNumberPages" value="0" /&gt;0
    &lt;input type="radio" name="rdNumberPages" value="1" /&gt;1
    &lt;input type="radio" name="rdNumberPages" value="2" /&gt;2
    &lt;input type="radio" name="rdNumberPages" value="3" /&gt;3
    &lt;input type="radio" name="rdNumberPages" value="4" checked="checked"
    /&gt;4
    &lt;input type="radio" name="rdNumberPages" value="5" /&gt;5
    &lt;input type="radio" name="rdNumberPages" value="6" /&gt;6
    &lt;input type="radio" name="rdNumberPages" value="7" /&gt;7
    &lt;input type="radio" name="rdNumberPages" value="8" /&gt;8
    &lt;input type="radio" name="rdNumberPages" value="9" /&gt;9
    &lt;input type="radio" name="rdNumberPages" value="10" /&gt;10
    &lt;input type="radio" name="rdNumberPages" value="other" /&gt;other
&lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>how can I make it in jquery that on selection of "other" from rdNumber automatically selects "other" radio button of "rdNumberPages"?
