In a terminal digit filing system using six-shelf files, how many shelves should be allocated per primary number?

• A. 6
• B. 12
• C. 24
• D. 3

Answer: (B)

In terminal digit filing, records are organized by the last two digits of the file number, which determine the shelf, while the remaining digits form the primary number used to sort within that shelf. With six-shelf files, you can place two terminal-digit ranges on each shelf, giving you twelve terminal-digit ranges per primary number. This setup provides enough subdivisions to keep records orderly within each primary number and still fit the six-shelf structure. So the allocation that matches this arrangement is twelve, reflecting the two-terminal-digit groups per shelf across the six shelves.
