              CHAIN BASE  METHOD CHAIN BASE METHOD In chain base method price changes are measured, of different years (I,e Current year) by comparing the prices with previous years of the selected data. For Example: Years: 2002, 2003, 2004, 2005, 2006, 2007 Prices: 10, 12, 13, 15, 16, 18 Here the arrows shows price comparison of every new year(current year) with its previous year(2003 with 2002, 2004 with 2003, etc.) Formula: I.N=Pn/Pr.(100) (Link Relatives). Here: "Pn" is price of current year. "Pr" is price of previous year. "100" is for obtaining the answer in "Percentage  Fixed Base method 1. It is easy to understand by a Common man as each year's price is Percentage of a fixed base year's price. 2. It is simple to calculate as the denominator denominator remains fixed for all the cases. 3. Here, the base period remains fixed. 4. It is very rigid, and so, it does not easily inclusion Permit accommodation of new items deletion of the outd...

Complement of a Set The  complement of a set  is the set that includes all the elements of the universal set that are not present in the given set. Let's say A is a set of all coins which is a subset of a  universal set  that contains all coins and notes, so the complement of set A is a set of notes (which does not includes coins). In this article we will discuss in detail the complement of a set, its definition along with properties, solved examples, and practice questions. What is the Complement of a Set? If universal set (U) is having a  subset  A then the complement of a set A which is represented as A' contains the elements other than the elements of set A. i.e., A' includes the elements of the universal set but not the elements of set A. Mathematically the complement of a set A is written as, A' = {x ∈ U : x ∉ A}. In other words, the complement of a set A is the  difference  between the universal set and set A. i.e., A' = U - A. Complement o...
