• A. LXXXXXI
• B. LLI
• C. CI

Answer 1

The correct option is C CI

Adding the chocolates Sam and Shreya have,
XX + LXXXI = ______

Step 1: Write the Roman numerals as Hindu Arabic Numerals.
XX = 10 + 10 = 20
LXXXI = 50 + 10 + 10 + 10 + 1 = 81

Step 2: Add the numbers.
XX + LXXXI = 20 + 81
= 101

Step 3: Write the sum in Roman numerals.
101 = 100 + 1
= C + I
= CI

Hence, XX + LXXXI = CI
