Explanation:
To understand why the correct answer is option 'D', let's consider a specific number represented by the symbols CD.
- When the places of the symbols are interchanged, the number becomes DC.
- To find the increase in the number, we need to subtract the original number from the new number: DC - CD.
Step 1: Converting symbols to their numerical values:
- In Roman numerals, C represents 100 and D represents 500.
Step 2: Finding the values of CD and DC:
- CD represents the number 100 + 500 = 600.
- DC represents the number 500 + 100 = 600.
Step 3: Calculating the increase:
- To find the increase, we subtract the original number (CD) from the new number (DC):
DC - CD = 600 - 600 = 0.
Step 4: Interpretation of the result:
- The increase in the number is 0, which means there is no increase when the places of the symbols are interchanged.
Therefore, the correct answer is option 'D' (200) because the number does not increase when the places of the symbols are interchanged.
