Hi.
First of all, inquiring about 'donation' as means of an admission procedure is not a valid question because 'donation' in reality means bribe to the senate or authorities in charge and which is by definition illegal. Admission into MGM’s JNEC is through direct admission procedure mentioned on this website (https://www.jnec.org/admissions.php) .
Admission into Shri Vishnu College of Engineering is either through EAPCET counseling or by enrollment with Shri Vishnu Engineering College for Women, Bhimavaram. Lateral Entry Admissions are on the basis of ECET Counselling.
The concept of donation has no legal foothold but it is still prevalent especially in kindergarten admission. There is no correct answer or perhaps any answer for "How much donation" depending on the level of admission this loot price will vary and if possible, avoid school which practice such acts.
Also remember that, The Right to Education Act prohibits both — the practice of schools accepting donations as well as interviewing children during admissions.
Good Luck
