MLV – CCCXXIV = ..... Hasil dari pengurangan di atas adalah ....

Correct Answer B. DCCXXXI

ExplanationThe given question is asking for the result of subtracting MLV (1065) from CCCXXIV (324). When subtracting Roman numerals, we need to follow the rules of Roman numeral subtraction. M (1000) cannot be subtracted from CCC (300), so we move on to the next highest value, L (50). L cannot be subtracted from CCC, so we move on to the next highest value, X (10). X can be subtracted from CCC three times, leaving us with C (100). V (5) cannot be subtracted from C, so we move on to the next highest value, IV (4). IV can be subtracted from C, leaving us with C (100) and IV (4). Therefore, the result is DCCXXXI (731).
