Please Recommend me a Book for DI-LR , And VARC , Anyone please ??

I would recommend you to try Arun Sharma book which is a pretty good book for all the 3 sections. It will help you in giving a better understanding of the questions solving patterns. It will also help you in strengthening your basics. As it also has a variety of questions with different difficulty levels so you can start from basics and can move on as you start feeling confident. For both DI-LR and VARC sections understanding the different type of questions is very necessary so going through books will help you in picking a strong command.

Along with this I would recommend you to solve last year paper and As very less time is left for the XAT exam so you need to brush up on your basics and start giving lots of online mock test and analyse solutions of each one of the thoroughly which will help you in overcoming your mistakes and come up with a strategy to definitely improve your marks and percentile. It will also help you to know about your strength and weakness which will help you in attempting easy questions first, that will reduce your chance of committing a silly mistake in an easy question or missing out an easy question. Along with this, you will also get enough time to attempt medium level difficult questions which will overall increase your speed with accuracy which leads to increase your percentile.

All the best!!
