If there also are such children who are not in the care of the surviving spouse, the portion of the allowance payable under this paragraph, assuming that these children were in the care of the surviving spouse, which is in excess of one hundred eighty dollars ($180) per month, shall be divided equally among all of those children and payments made to the spouse and other children, as the case may be.

(a)
If there is only one such child, such child shall be paid one hundred eighty dollars ($180) per month;
(b)
If there are two such children, such children shall be paid three hundred sixty dollars ($360) per month divided equally between them; and
(c)
If there are three or more such children, such children shall be paid four hundred thirty dollars ($430) per month divided equally among them.

No allowance shall be paid under this subdivision, while the surviving spouse is receiving an allowance under subdivision (1) of this section, or while an allowance is being paid under subdivision (2)(c) of this section. The allowance paid under this subdivision shall be seventy dollars ($70) per month while an allowance is being paid under subdivision (2)(b) of this section.
