Answer: Option C. -> LXX
:
C
We know that X = 10 and L = 50.
When a Roman numeral with the larger value is on the left, we add the values together and when it is on the right, we subtract the values.
∴ XL = 40
Also,XXX = 10 + 10 + 10 = 30.
∴ XXX + XL = 40 + 30 = 70
But, 70 = 50 + 10 + 10 = L + X + X = LXX.
∴ XXX + XL =LXX

Answer: Option B. -> CXVI
:
B
Let us first convert the Roman numerals into Hindu-Arabic numerals.
When a Roman numeral with the larger value is on the left, we add the values together and when it is on the left, we subtract the values.
∴ XLVI = (50 - 10 ) + 5 + 1
= 56 - 10
= 46
LXX = 50 + 10 + 10
=70
∴ XLVI + LXX = 46 + 70 = 116
But, 116 = 100 + 16 = C + XVI =CXVI.
∴XLVI + LXX = CXVI
