Query tag added for that.</p>\n \t\t <p>Also very cumbersome use of variables. But no change proposed for now.</p>\n \t\t <p>Checked calculation, OK. Added tested1 tag.</p>\n \t\t <p><strong>21/12/2012:</strong></p>\n \t\t <p>Although asks for solution to 2 dps, there is no rounding as the raw values are to 2 dps. Added sc tag for possible scenarios.</p>\n \t\t",
