Answer

Brief Explanations:

To solve this, we analyze the library sorting rule: books are sorted by their codes, with the letters first (e.g., PN 210 comes before PN 225). For the book PN 225:

  • Compare with NP - coded books: "PN" and "NP" are different. Alphabetically, "NP" comes before "PN" (since N < P? No, wait: when comparing "NP" and "PN", the first letters are N vs P. N comes before P, so NP - coded books come before PN - coded books. So PN 225 is after NP - coded books, eliminating A and B.
  • Compare with PN - coded books: For PN 220 and PN 225, since 220 < 225, PN 220 comes before PN 225. So PN 225 should be after PN 220. Check options:
    • Option C: Before PN 220? No, because 220 < 225.
    • Option D: After PN 220? Yes, because 220 is less than 225, so PN 225 comes after PN 220.
    • Option E: After PN 230? No, because 225 < 230, so PN 225 comes before PN 230.

Answer:

D. After a book coded PN 220
