b. 25. 
c. 13 b. 
d. 10. 
e. 26. 
f. 27. 
2. Pro-rating: The formula in use for operators who have had 
training in both adding and extending is: 
.10 X r8 + .10 X ri5 + -io X ri3b + .20 X rio + -25 X 
r26 + -25 X r27 = R. 
Division is comparatively little used. Where it is re 
quired, an appropriate test is included. Where operators 
with special experience in adding or in extending alone are 
required, the more important test is valued at 40% the 
less at 10%. Where operators who are just out of school 
and who have not yet acquired speed are desired, the pro 
portional value given to the tests shall be .10, .15, .10, .30, 
.20, and .15 respectively. 
3. Standards: Above .70 to be recommended; .60 to .70 to be 
recommended for a trial.
