The Consumer Price Index or CPI is an index used to calculate the ______ of a country.
retail inflation
Understanding the Consumer Price Index (CPI)
The Consumer Price Index (CPI) is a key economic indicator used in many countries. It helps us understand how the prices of everyday goods and services are changing over time.
What Does the CPI Measure?
The CPI measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. This market basket includes items like food, housing, clothing, transportation, medical care, recreation, education, and communication.
By tracking the price changes of these items, the CPI provides a snapshot of the cost of living for consumers.
CPI and Inflation
The primary use of the CPI is to calculate the rate of retail inflation. Retail inflation, also known as consumer inflation, is the rate at which the general level of prices for goods and services is rising, and subsequently, the purchasing power of currency is falling.
A rise in the CPI indicates that, on average, consumer goods and services are becoming more expensive. This is a measure of inflation that directly impacts households.
Why Other Options are Incorrect
- forex: Forex refers to the foreign exchange market, where currencies are traded. CPI is not used to calculate forex rates.
- GDP growth: GDP (Gross Domestic Product) growth measures the increase in the total value of goods and services produced in a country. While inflation can affect nominal GDP, CPI itself is not used to calculate the rate of GDP growth.
- Income tax: Income tax is a government levy on income. CPI is not used to calculate individual or corporate income tax amounts.
Therefore, the Consumer Price Index (CPI) is specifically used to calculate the retail inflation of a country.
Important Questions from Miscellaneous
A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
