which college i can get with 98.4 percentile and obc category in mhtcet ??

98.4 percentile means you can expect a general rank within the range of 2000 to 4000. Now this is an assumption based on the details like Number of candidates appeared in the examination, qualified candidates, highest score etc.
If you go through last year's cutoffs, then you can expect

• Metallurgical Engineering in COE, Pune
• Production, Textile Technology in Veermata Jijabai Technological Institute
• Surface Coating Technology, Fibres and Textile Processing Technology in ICT Mumbai
• Electronics, Electronics and Telecommunications Engineering in Sardar Patel Institute of Technology
• Computer Science and Engineering, Information Technology, Mechanical, ETC, EEE in Government College of Engineering Aurangabad
• Computer Engineering, Information Technology, Mechanical, ETC in Pimpri Chinchwad college of Engineering

etc. But keep in mind that these are based on last year's data and this year the cutoffs can change. To get complete list of all colleges you can get based on your rank use this link http://www.careers360.com/mht-cet-college-predictor
