I am getting confused with the terms like annual percentage growth, cummulative growth for 2 year/annual and many terms like this in DILR section and making mistake in calculating that is there a place where I can find these different set of formulae and concepts for understanding? Thanks in advance

Hi Varshith Yelleti,
You can go through DI videos in our video series section. Make sure you know the basic formulae used to calculate the percentage growth. This is something which varies from question to question. Try to practice as many sets as possible in DI. You will eventually understand the logic behind calculations done for different types of questions.
Hope this helps!
