    The aims of carrying out project work are:a.to apply and adapt a variety of problem- solving

    strategies to solve problems;

    b.to improve thinking skills;c.to promote effective mathematical communication;d.to develop mathematical knowledge through problem

    solving in a way that increases students interest and

    confidence;

    e.to use the language of mathematics to expressmathematical ideas precisely;

    f. to provide learning environment that stimulates andenhances effective learning;

    g.to develop positive attitude towards mathematics.

    a. Describe in briefi. Price Index

    ii. Weightageiii. Composite index

    PRICE INDEXMeasure of change in a set of prices, consisting of a series of numbers arranged so that a comparison of

    the values for any two periods or places will show the change 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 basket of goods in a base period,

    then use the prices for those goods to examine change over 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

    familiar indexes 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 as food, 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 use

    the 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.

    WEIGHTAGEWeightage means preference of one product in comparison to other product. On the other hand we can

    say weightage means giving the value of the specific or particular matter or subject higher or lesser thanthat of or in comparison to similar 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 weightage and last but not

    least less the Uses of Banks facility, more the benefit weightage and moral dimension or ethical values.

    COMPOSITE INDEXA grouping of equities, indexes or other factors combined in a standardized way, providing a useful

    statistical measure of overall market or sector performance over 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.

    We often hear complaints from the public about inflation. It causes an increase in the household

    expenditure in a family. The household expenditure for every family is different.

    Comment :

    My family used up money on education as education is important in our life. My family often buys new

    books every weeks as for us reading is the key to success in life no matter how much the cost of the

    book. Instead, my family used least money on recreation due to busy of works and studies.

    b. If we want to compare the cost of living from one year to another, we have to calculate the priceindex that involves some of the items mentioned above.

    i. In order to calculate the price index of all the items above, we have to consider the averagemonthly expenses of any previous year as the base year. Select the appropriate year as the

    base year.
