Dear Sir,

Please tell me Roman no. of 180 ?

CXXC OR CLXXX and Why ?

Hi!

 

In Roman numeral X, L and Y stand for the numbers 10, 50 and 100 respectively. There is a rule while writing Roman numeral. The rule is that Two or more smaller numerals (with respect to their value) cannot be written in between two bigger numeral.

 

Among X and C, C is smaller numeral as compared to C. So, we cannot write two X between two C. Thus, writing of CXXC is not logical valid.

 

Now, CLXX X = 10 + 50 + 10+ 10 + 10 = 180

 

Thus, the Roman numeral for 180 is CLXX X but not CXXC.

 

Hope! This will help you.

Cheers!!!
