ANNEX
INSTRUCTIONS FOR OBTAINING THE APpropriate Factor from Table I
For Officers aged 28 years or more
I. Read off from the table the factor for the officer's age at his last birthday and his completed years of service.
II. Read off from the table the factor for ten years' service and the officer's age in years and completed months by interpolation arithmetically.
III. Divide by 120 and multiply the result by the number of completed months of service not excecding 120, adjusting the answer to the nearest second demical place (when the third decimal place is 5 exactly, take the next highest second place).
IV. The greater of I and III is the factor required.
For Officers under the age of 28 years
1. Read off from the table the factor for the officer's age at his last birthday and his completed years of service.
II. Read off from the table the highest factor given against the officer's age in completed years and interpolate arithmetically for the factor corresponding to his age in years and completed months.
III. Divide II by the figure corresponding to the number of months contained in the years of service against which the factor in II was read off and multiply the result by the number of completed months of service, adjusting the answer to the nearest second decimal place (when the third decimal place if 5 exactly, take the next highest second place).
IV. The greater of I and III is the factor required.
INSTRUCTIONS FOR OBTAINING THE Appropriate FACTOR FROM TABLE II, III OR IV
I. Read off from the Table the factors for the officer's age-
(a) at his last birthday ;
(b) at his next birthday.
IL. Divide the difference between I(a) and I(b) by twelve and multiply by the number of completed months of age since the last birthday.
III. If I(b) is greater than I(a), add II to I(a).
If I(b) is less than I(a), subtract II from I(a).
III is the factor required.
In calculating factors by interpolation in respect of Tables II to IV the calculations should be taken to three places of decimals.
