  In this article we will learn how to deal with successive percentage increase/ Decrease. Problem based on successive percentage increase/ Decrease are very frequent in competitive examinations. Understanding Successive percent increase/decrease is very important. Since successive percentage increase/decrease is used while solving problems related to Profit, Loss, Discount & Compound Interest problems. Let us understand first concept of Multiplying Factor (M.F.) Multiplying Factor (M.F.)                                                        Case 1:   When a quantity is increased by certain percentage. A) Suppose we have to increase a value 120 by 10%. What will be the final value? Final Value= Initial Value + 10% of Initial Value                 ...

  In this article you will learn how to calculate Percentage Growth/Increase/Decrease in Data Interpretation Questions. Here I will explain how to use concept of  Multiplying Factor  for solving Percentage Growth, Increase/Decrease questions quickly.  You are suggested to read concept of  Multiplying Factor  first, and then come back to read this article. Let us take few examples: Example:  XYZ motors limited sold 7000 Scooters in year 2012. If sale of scooter is increases by 10% in year 2013. Calculate no of scooters sold in 2013. Solution:    Increase in scooter sale = 10% === è  M.F. = 1.1 Final Value = Initial Value * M.F. Scooter sales in 2013 = M.F. X 7000 = 1.1 X 7000 = 7700. Let us understand how to use  Multiplying Factor   while solving DI questions. Example: The below Graph represents Bajaj Auto’s sales volume in different segment from year 2010 to 2013. Question:  What is percentage growth in sales volume...
