PRACTICALS MEIN LAFDA?

Ye school mein ek sir hai ye practicals mein 30/30 dilane ka paisa le rhe. Paisa toh main dedu par ye thode sacche nahi sahi lag rhe. Keh rhe the kisi aur teacher ko nahi batana hamari seedha principal se baat hui hai. Fir kehne lage ye sadiyo se chala aa raha hai aur hamne bhi kiya tha. Agar ye fraud nikle toh Mai maanlo paise dedu, na padhu practical ke liye aur number bhi na mile toh khatam ho jaayega sb

Kya yaha pe kisi se iss vishay mein kuch charcha hui thi?
