3.—(1) Where as well as any relevant child there are other children to whom allowances are payable in respect of the death of the same person and any of the relevant provisions apply, the allowances payable to those other children (“the other allowances”) shall be increased as hereinafter provided.
(2) If paragraph 2(a) applies in the case of any relevant child, then, without prejudice to sub-paragraph (3), the annual amount of each of the other allowances shall be increased by an amount equal to his excess remuneration divided by the number of other allowances.
(3) If paragraph 2(b) applies in the case of any relevant child, then, without prejudice to sub-paragraph (2), each of the other allowances shall be recalculated as if the relevant child were not entitled to an allowance.
(4) Notwithstanding the provisions of sub-paragraphs (2) and (3), no child shall by virtue of those provisions receive an allowance greater than that to which he would be entitled if no relevant provision applied in his case.
