Instead of putting the variable inside the <xsl:choose>, put the
<xsl:choose> inside the variable:

  <xsl:variable name="newValue">
    <xsl:choose>
      <xsl:when test=". = 1">10</xsl:when>
      <xsl:when test=". = 2">15</xsl:when>
      <xsl:when test=". = 3">25</xsl:when>
      ...
    </xsl:choose>
  </xsl:variable>

and then reuse $newValue wherever you need it.

If you need it in different templates, on the other hand, then you
should create a separate template that contains the <xsl:choose> and
call that template whenever you need the relevant value; the value
itself won't be reused, but the code that calculates it can be. Let us
know if you want to see how to do that.

Cheers,

Jeni
