Answer 2

VX is not meaningful. (Option a)

• The given options are just numbers expressed in Roman as letters where V is used to denote 5 and X for 10.
• When a letter is placed before another, its value is reduced from the latter and when placed to the right, value is added.
• So, XV is 10+5=15. XXV is 10+10+5=25 and similarly, X-XXV is 10+10+10+5=35.
• But VX is 10-5=5 and 5 can be written as V itself.
