Marginal Relief and augmented profits

Can someone just quickly try to explain something to me.

From the technical articles for F6, it says:
“Marginal relief eases the transition from the small profits rate to the main rate of
corporation tax where augmented profits fall between £300,000 and £1,500,000.”

So, from that, it reads like, any company with augmented profits that fall between £300,000 and £1,500,000 is able to claim marginal relief (using the 1/100 x (U-A) x N/A formula) – so far so good. Augmented profits that are either below £300,000 or over £150,000 don’t qualify for marginal relief.

Why then, in question 2 from the June 2013 paper can the company in question claim marginal relief when its augmented profits are only £252,000 (total profits of £213,000 plus franked investment of £39,000).

Total augmented profits is £252,000 which is below the £300,000 threshold – yet the answers say that marginal relief is to be claimed.

It’s been a long day, so probably something very simple – someone please help?
