Is this kind of sentence common in Romanian? Using the definite article with a number in English is odd, and usually implies special emphasis on the items referred to by the quantity. These items are usually supplied by context. E.g. "The ten," could refer to the ten people on a really good/special team.
Think of the million as a sum of that amount in dollars (or euros) in cash in an attache case with a combination lock, and you and your partner are delivering it to me in Bucharest. I am eyeing you two calmly. "Do you have the million? Do you have the code? Nothing else matters!" ("Aveți milionul? Aveți codul? Nimic altceva nu contează!") :)
