Should i concentrate more on XAT as i felt it was more on verbal side,low cut offs and with CAT 20 days away, my quant is shamefully low

Hi Rakesh! As of now, focus on CAT since it is exactly 20 days away. Practice as many Quant questions as possible from various topics so that on the exam day you are not unfamiliar with the question types. Among all the possible topics, you should be able to recognise those questions which you can tackle and otherwise. Build a proper section wise strategy for the exam day and stick by it. Take sectional Quant mock and a full length CAT everyday. In the mean time, work on the types of mistakes you are committing to correct them. As far as XAT is concerned, if you feel you are weak in Verbal Ability and Decision Making, build a habit of reading and practising Reading Comprehension and other verbal ability questions to get a grip over the section. But again, now that CAT is a priority, you should focus on that. Also, since the sections are common in both tests (except Decision Making), revising VARC for CAT will help you recover for XAT Verbal section as well. All the best!
