INTRODUCTION INDEX An index depend is a plowshare ratio of impairments, quantities or sets analyze dickens time checks or ii points in time. The time full point that serves as a basis for the similarity is called the tooshie period and the period that is compared to the stem period is called the disposed or current period. A value index ginmills the change in the specie value of an item (or stem of items) oer time whereas a bar index measures the non-monetary value of an item (or a stem of items) over time.An index repress that represents a dowery affinity of the twist of cars sold in a granted calendar month as compared with that of a foot month is a cadence index. A price index represents a comparison of prices amid cardinal time periods and, finally, a value index is one that represents a comparison of the broad(a) value of action or sales in two time periods without regard to whether the observed remainder is a result of differences in quantity, price or both. index number numbers are also dissimilariated according to the number of commodities or products included in the comparison.A transparent index, also know as a relative, is a comparison involving only one item but an index whose counting is based on some(prenominal) items is cognize as an aggregate or escalate index. A very famous pillow slip of a multiform index is the retail Prices Index (RPI), which measures the changes in speak tos in the items of wasting disease of the average household. In economicsandfinance, an index is a statistical measure of changes in a representative assort of individual data points. These data may be derived from any number of sources, including union performance, prices, productivity, and employment.Economic indices (index, plural) course of reckon economic health from contrary perspectives. Influential global financial indices such as theGlobal Dow, and the NASDAQ Composite tether the performance of selected large and powerful companies in order to evaluate and predict economic trends. TheDow Jones Industrial Averageand theS& angstromP 500p brimarily track U. S. securities industrys, though some legacy world-wide companies are included. The ConsumerPrice Indextracks the change in prices for divergent consumer goods and services over time in a unvaried geographical location, and is integral to computer sciences employ to djust salaries, stick around quest judge, and tax thresholds for inflation. The GDP DeflatorIndex, or real GDP, measures the level of prices of all new, domestically produced, final goods and services in an economy. trade performance indices include thelabour market index / job indexand patentedstock market index investing funds in struments offered bybrokerage houses. Some indices bring out market variations that discountnot be captured in other ways. For example, theEconomistprovides aBig mack Index that expresses the adjusted cost of a globally ubiquitous Big mack as a perpennyage over or under the cost of a Big macintosh in the U.S. with a U. S. dollar (estimated $3. 57). Norway prices reflect most comparatively expensive Big Mac, at an 84% outgrowth over U. S. prices, or $6. 5725 U. S. The to the lowest degree relatively expensive Big Mac price occurs in Hong Kong, at a 52% reduction from U. S. prices, or $1. 71 U. S. The Big Mac index is used to predict currency values. From this example, it would be fictive that Hong Kong currency is undervalued, and provides a currency investment opportunity. An index number is a percentage ratio of prices, quantities or values comparing two time periods or two points in time.The time period that serves as a basis for the comparison is called the base period an d the period that is compared to the base period is called the given or current period. A price index measures the change in the specie value of an item (or group of items) over time whereas a quantity index measures the non-monetary value of an item (or a group of items) over time. An index number that represents a percentage comparison of the number of cars sold in a given month as compared with that of a base month is a quantity index.A price index represents a comparison of prices between two time periods and, finally, a value index is one that represents a comparison of the total value of production or sales in two time periods without regard to whether the observed difference is a result of differences in quantity, price or both. Index numbers are also differentiated according to the number of commodities or products included in the comparison. A wide index, also known as a relative, is a comparison involving only one item but an index whose calculation is based on several i tems is known as an aggregate or composite index.A very famous example of a composite index is the Retail Prices Index (RPI), which measures the changes in costs in the items of expenditure of the average household.

Explain the meaning of compound interest and simple interest. purport a better way of keeping the money in this bank. State a sufficient period for keeping the money for each plan. Explain why. Solution y Dictionary (source Oxford Advanced Learners Dictionary 6th Edition) Compound interest * Interest that is paid both on the original amount of money relieve and on the interest that has been added to it. dim-witted interest * Interest that is paid only on the original amount of money that you invested, and not on any interest that is earned. Simple interest is suitable for savings in a short period. It is because of its interest is higher than compound interest and it is paid only on the original amount of money that you invested , and not on any interest that is earned.For example, when you keep RM50 000 with an interest of 5% for 2 years, then you will gain RM 5 000 after two years. So the total amount in the bank is RM 55 000 after two years. When one keeps RM 50 000 with the interest of 3. 5 % of compound interest for 2 years, then you will gain RM3 561. 25. So the total amount in the bank is RM 53 561. 25 after two years. Compound interest is suitable for savings in a long period. It is because of the original amount of money salve and on the interest that has been added to it. For example, RM50 000 for the plan of 3. 5 % of compound interest plan for 30 years then we will gravel RM 140 339. 9 in our saving account. But when one keeps RM 50 000 for the plan of 5 % of simple interest for 30 years, then we will only guard RM 125 000 in our savings account. Therefore, it is better to save in the compound interest plan account for long-term savings and simple interest for short-term savings. FURTHER EXPL ORATION When Ahmad was born, his parents invested an amount of RM 5 000 in the Amanah Saham Bumiputera (ASB) for him. The interest rate offered was 8. 0% p. a.
