Question: 1 kg biriyani rice how many person can eat?
Answer: Ideally 1 kg of biryani means they will use 1 kg RAW Rice and make that biryani. No of pieces is proportionate to that quantity or how you ask them to make . If it is literally 1 kg of biryani by weight then only 2 people with normal appetite or 3 -4 people with below average appetite .
