Private Placement vs Public Issue in Company Law: Dilli Ka Raja Kya Hai, aur Daraar Ka Duniya ka?

Meri confusion hai ismein, sabhi ko pataa hai. Private Placement aur Public Issue mein kya fark hai? Maine padha to private placement mein investment kisi specific group se hota hai, aur wo group koi company mein invest karta hai. Lekin public issue mein yeh kuch alag hai na? Ismein investment sab log karte hai, jaise ki IPO mein. Tum sabhi kya kahoge, ke ismein kya sahi hai? Iska application kis form mein hota hai? Abt koi public issue kiya to private placement karna padta hai ya nahi? Please, ek line mein batayein.
