In the following options, the natural numbers and their equivalent roman numerals are given. Find which option is incorrect.

• A. 60 = LX
• B. 28 = VIII
• C. 15 = XV
• D. 35 = XXXV

Answer 1

The correct option is B 28 = VIII

For finding the Roman numeral of any number, write the number in expanded form and convert each term to Roman numerals.

15:
15 = 10 + 5
= X + V
= XV

This is correct.

60:
60 = 50 + 10
= L + X
= LX

28:

28 = 20 + 8
= XX + VIII
= XXVIII

But it is given as VIII in the options.

Hence, this is incorrect.

35:

35 = 30 + 5
= XXX + V
= XXXV
This is correct.

Hence, the roman numeral for the number 28 is incorrect.
