Section 80C: Kyun Laga Raha Hai Main Bemisal?

Maine socha tha 80C ke under charitable donations ka deduction zaroor mil sakta hai, par phir woh ek article padha jahan likha tha ki ye deductions sirf 10% hai, bas. Kyun main 80C ke under charitable donations ka pata chalne se behtar jankari nahin chal rahi? Maine socha tha maine ye section acchhi tarah se samajh liya hua hai, par woh paper aaya aur main samajh gaya koi bhi nahi!

Maine suna hai ki yeh section bhi sirf kuch hi cases mein applied hota hai, par kya ye sabhi cases hi public-private interface ke under hai?
