Hey harsh!

Considering the previous year DUJAT cutoffs , your percentile in DUJAT is so low to get a seat in any of the colleges of DU.  You can only expect a seat in DU if your rank is under 2k and your percentile is more than 90. 

Sorry for the disappointing answer but since your 12th score is good enough , so you can try to get a good percentile in DUJAT next year.

Hope  it helps!
