How many 'möngö' are there in a Mongolian 'tögrög'?

Did anybody know the answer to this question? Go to the top of the class if you did!

Olly, Hardly! When you think of monetary systems, how many do you know of where there are not 100 sub units? Dollar and cent , Euro and cent , pound and penny etc to name a few .

Guessed by totaling the coins on the pic that's close to 100
