Test: Roman Numerals- 1 - Class 4 MCQ

XXXIV = XXX + IV
= 30 + 4
= 34

When a smaller numeral is placed between two larger numerals, it is always subtracted from the larger numeral immediately following it.
Example: XIX = 10 + (10 − 1) = 10 + 9 = 19

LVV is not written correctly because V cannot be repeated.

XV = X + V = 10 + 5 = 15
XXV = XX + V = 20 + 5 = 25
XLII = XL + II = 40 + 2 = 42
LXXIV = LXX + IV = 70 + 4 = 74
Hence, the correct ascending order is 15 < 25 < 42 < 74 or XV < XXV < XLII < LXXIV.

LXXXIV = LXXX + IV
= 80 + 4
= 84

65
= 60 + 5
= LX + V
= LXV

XCVIII
= XC + VIII
= 90 + 8
= 98
XVIII
= X + VIII
= 10 + 8
= 18
98 > 18
Hence, the statement XCVIII > XVIII is true.
XCVIII = 98
XVIII = 18
98 > 18
Hence, the statement XCVIII < XVIII is false.
XCVIII = 98
XVIII = 18
98 > 18
Hence, the statement XCVIII = XVIII is false.
XCVIII = 98
XCVII = 97
98 > 97
Hence, the statement XCVIII < XCVII is false.

The Roman numeral D represents 500.

X can be subtracted from L and C only.

Repetition of the basic symbols I, X, C, M when writing Roman numerals means addition.
E.g. X=10 And if we repeat this X two times then it will be10+10 which is 20
