Hello Jitender,
First of all keep in mind one thing that you cannot learn Mathematics, it can only be done by practice. More you practice, more you will able to solve the questions. Try to love mathematics, try to build up your interest in it.
Tips for mathematics problem solving:
1. Practice, practice and more practice.
2. Review errors: If you have made any mistakes, you should review them and understand where your problem solving skills let you down. Understanding how you approached the problem and where you went wrong is a great way of becoming stronger and avoiding the same mistakes in the future.
3. Master the key concepts: Do not try to memorize the processes. This is counter-productive. It is much better and rewarding in the long-run to focus on understanding the process and logic that is involved. This will help you understand how you should approach such problems in the future.
4. Understand your Doubts: Sometimes you can get stuck trying to solve part of a mathematics problem and find it difficult to move on to the next stage. It is common for many students to skip this question and continue on to the next. You should avoid doing this and instead spend time trying to understand the process of solving the problem. Once you have grasped an understanding of the initial problem, you can use this as a stepping stone to progress to the remainder of the question.
5. Create a distraction free study environment: Mathematics is a subject that requires more concentration than any other. A proper study environment and a distraction free area could be the determining factor when solving complex equations or problems in geometry, algebra or trigonometry.
6. Create a mathematical dictionary: Mathematics has specific terminology with a lot of vocabulary. I would suggest you to create notes or flashcards with all the concepts, terminology and definitions you need to know.
All the best.
