La Chacolaterie Somalis

Mary dreamt of buying a somali kitten for a long, long time.
She had everything prepared for the kitty, and she had saved all the money she got
at her birthdays and for Christmas to this avail.

Checking how much she had, she noticed that :

her parents had already given her half the price of the kitten,
her grandma one eighth,
her godfather a tenth,
her elder brother one twentieth.

But she was still missing 180 euros.
How much does the desired kitten costs ?

... I'm giving up...
