Yes there is a chance. IPU generally gives preference to NIMCET exam aspirants but NIMCET is mainly for NITS. That means that most of the students might haven't registered for admission under IPU. In that case assume we have 50% of seats left.

Now coming to IPU MCA CET exam, they gave rank to around 1250 aspirants. You are under first 50% of the rank holders. And Delhi students too have 75% reserved seats. That means that you might get to choose between 2 colleges for admission. Do note that these colleges will be the last choice of many students as all the other colleges will be preferable against them. It's applicable to candidates of UP domicile only. And it's the first time they're doing it. I really don't know how many UP candidates had appeared for NIMCET out of which how many are non-qualified & are gistering for HBTU. But I think you have decent chances because under 800 people will go for NITs and from 800 to 874 there won't be much candidates belonging to UP, may be even 0. Because the rush in NIMCET comes from MP mostly (u know JMA). You have a high probability of being accepted at HBTU. My estimations are closer enough.
