Generally speaking, most private engineering colleges in India reserve around 65%–75% of seats for merit-based admissions (through counselling or entrance exams like JEE Main or state-level tests), while the remaining 25%–35% fall under the management quota .

Now, if you’re asking “how many seats were filled through the merit list last time (based on last year’s cutoff)” , then in most cases, CSE seats get filled almost completely through the merit list in reputed colleges because it’s the most in-demand branch. Only a small portion, sometimes 5–10% , might remain for management quota after the final counselling round.
