If you're serving it as a main course, you should allow at least 125 grams (uncooked weight) of tortellini per person, assuming you're not serving anything else substantial with the pasta . (125g is probably what you would expect a decent restaurant to serve as a main; enough for an average-sized women, if there's also some veg/salad, but may still leave a man hungry.)
This is really the minimum you should allow for; if you're expecting your guests to be exceptionally hungry, or they're all men with the build of Rugby-players, or they're all students, or you're not serving a starter, it may be best to allow 175g per person.
This means that for 12, you require at least 1500g tortellini (1.5kg), to 2100g (2.1kg).
As an entree - figure on 50 cups. If there's not much added (ie: chicken breast, vegetables, etc) perhaps 75 to be safe (ie: buffet style serving where you can't do portion control). If you're serving it as a pasta salad / side, 25 cups. If you're serving it as an entree, but with cubed chicken breast & vegetables & sauce, you could probably get away with 25 cups.

50 to hundreds. Depends on how much a person can eat.
About 50 pounds!
Can pick them up for one Pound or a Bit over at Asda. Chosen by you range
Allow about a half pound per person. That means you would need about 25 pounds to feed 50 people.
About 13 pounds of chicken should feed 50 people.
What is a "people quart"
The chicken weight varies due to bone and boneless.It would approximately take about 115 pounds to feed 200 people.About 60 pounds will feed up to 50 people.

Depends on the size. If its about 25 lbs you need 2 turkeys.
How many quarts you need to feed 50 people depends on what you are making, and if there will be other foods. If there are other foods, you should figure four ounces per person. There are 32 ounces in a quart so each quart will feed eight people. Therefore, you would need a little over six quarts to feed 50 people.
