Answer 2

Answer :-

How much money € do you earn in a month?

Explanation :-

We are using 'much' here because we are expressing the amount of money. Money received is an 'amount' that he / she is receiving.

'Many money' is not used here because, the word 'many' is always used when we are expressing a quantity. But, money is an amount and not quantity, and thus, the word 'much money' is used.
