Dividend from associate

Sir, i came across this question in Kaplan kit, to prepare the Csop/l of Laurel Co.

Laurel’s investment income consists of,
– its share of a dividend of $500,000 paid by Rakewood in August 20X6.
– a dividend of $200,000 received from Artic, a 25% owned associate which it has
held for several years. The profit after tax of Artic for the year ended
30 September 20X6 was $2.4m.

Parent’s investment income is 500k and sub’s 400k.

And the given answer for the same is,

Investment income (400 × 9
/12) 300k
Income from associate (2,400 × 25% based on underlying earnings) 600k

My question is that why they haven’t deducted the 200k dividend received from the associate but also took the full PAT made by the associate?
Clearly, parents investment income includes the 200k received from the associate, so inorder to avoid double counting of the profit it should be deducted, right?
(I assume what they’ve done is,
Total investment income 500(parents)+400*9/12(sub)-500(dividend from sub) = 300k).
((Sub is acquired part-way through the year))
