The answer Grandpa wants to hear is:
D: A or B
For a given Roman numeral, we need to:
1. Spell that number out in English,
2. Find elements in the Periodic Table whose symbols can be combined to spell the same word,
3. Give as our answer a number made up of those elements' atomic numbers concatenated together.
X is 10 (TEN) in Roman numerals.
TEN = Tellurium (Te) + Nitrogen (N).
The atomic numbers of these elements are 52 and 7.
I is 1 (ONE) in Roman numerals.
ONE = Oxygen (O) + Neon (Ne).
The atomic numbers of these elements are 8 and 10.
So for IX:
IX is 9 (NINE) in Roman numerals.
NINE = Nickel (Ni) + Neon (Ne).
The atomic numbers of these elements are 28 and 10.
NINE = Nitrogen (N) + Iodine (I) + Neon (Ne).
The atomic numbers of these elements are 7, 53 and 10.
Hence IX=75310 as well!
Thus our answer is:
D - since IX is equivalent to both 2810 and 75310 using his method!
