Paragraph 3
The number of years arrived at under this paragraph is that which is obtained by—
taking the number of years between (inclusive) the year in which the woman married the husband and (inclusive) the year in which the marriage was terminated; and
multiplying it by the number of the husband's reckonable contribution years falling wholly before the date of that termination, and
dividing it by the number of years in his working life falling wholly before the date of that termination;
if the resultant quotient is not a whole number, rounding it up to the nearest whole number; and
adding to the number of years arrived at under paragraphs (a) and (b) above any number of years—
before that in which she became married to the husband, and
after that in which the marriage was terminated, being years for which her own earnings factor was sufficient for satisfaction by her of paragraph (b) of the second contribution condition.
