Hello Aryan, 

for non-muslim category: a marks above 200 is very much desirable for JMI in BArch, if you have marks around 170-200, you may make it to the 1st or 2nd counselling list.

for muslim category: around 150 is enough to be in a safe spot. 

Last year's cutoff were:

Gen non-muslim:  200
Muslim 180
Muslim OBC/ST 170
MUSLIM WOMEN 160
JAMIA INTERNAL 140
PWD 127
Kashmiri Migrant 180

Hope this helps
