    a. Describe in brief i. Price Index ii. Weightage iii. Composite index PRICE INDEX

    Measure of change in a set of prices, consisting of a series of numbers arrangedso that a comparison of the values for any two periods or places will show thechange in prices between periods or the difference in prices between places. Price indexes were first developed to measure changes in the cost of living in order to determine the wage increases necessary to maintain a constant standard of living. There are two basic types. Laspeyres-type indexes define a market basketof goods in a base period, then use the prices for those goods to examine changeover space and time. In its simplest form, this is simply the ratio of what those goods cost today to what they cost in the base period. The two most familiarindexes of this type are the consumer price index (CPI) and the producer price index (PPI). The CPI measures changes in retail prices in such component parts asfood, clothing, and shelter. The PPI (formerly called the wholesale price index) measures changes in the prices charged by manufacturers and wholesalers. Paschal-type indexes define a market basket of goods in the current period, then usethe prices of those goods from past periods. The most familiar index of this type is the GDP deflator, used in the U.S. in the national income accounting to differentiate amounts in constant dollars from those in current dollars. WEIGHTAGE

    Weightage means preference of one product in comparison to other product. On theother hand we can say weightage means giving the value of the specific or particular matter or subject higher or lesser than that of or in comparison to simila

    r one. The factors of weightage are The more risk, the more weightage, the longer the period, more the risk, more the uses of Banks facility, less the weightageand last but not least less the Uses of Banks facility, more the benefit weightage and moral dimension or ethical values. COMPOSITE INDEX

    A grouping of equities, indexes or other factors combined in a standardized way,providing a useful statistical measure of overall market or sector performanceover time. Usually, a composite index has a large number of factors which are averaged together to form a product representative of an overall market or sector.For example, the Nasdaq Composite index is a market capitalization-weighted grouping of approximately 5,000 stocks listed on the Nasdaq market. These indexes are useful tools for measuring and tracking price level changes to an entire stock market or sector. Therefore, they provide a useful benchmark against which to

    measure an investor

    s portfolio. The goal of a well diversified portfolio is usually to outperform the main composite indexes.

My family often buys new books every weeks as for us reading is the key tosuccess in life no matter how much the cost of the book.

    b. If we want to compare the cost of living from one year to another, we have tocalculate the price index that involves some of the items mentioned above. i. In order to calculate the price index of all the items above, we have to considerthe average monthly expenses of any previous year as the base year. Select theappropriate year as the base year.
