What Number Corresponds to Eyeliner in This Brainteaser?

[The riddler]

Hello all, i found a menser teaser in the daily express, this is the first Menser teaser where i can not find any connection between anything.


The order of the number for various cosmetics are as shown. What number is EYELINER?

MASCARA-1100
CONCEALER-250
LIPSTICK-152
LIPGLOSS-101
EYELINER-?

I don't know the answer to this brainteaser and i could not find it on the internet, if anyone has any ideas about how the hell this brainteaser works please post them.

Thanks for any replies

EYELINER is 51.

Roman numerals?

M+C = 1100
C+C+L = 250
L+I+I+C = 152
L+I+L = 101
L+I = 51

OOOOOOOOH, sadly I've never done Roman numerals, well done and thanks for helping.
