The prices of a commodity in the year 1975 and 1980 were 25 and 30 respectively taking 1980 as base year the price relative is :
Taking 1980 as base year......
Pn/p0*100
Then,
25/30*100
=83.3333
And the answer is 83.33
The average price of certain commodities in 1980 was Rs. 60 and the average price of the same commodities in 1982 was Rs. 120. Therefore, the increase in 1982 on the basis of 1980 was 100%. 80 the decrease should have been 100% in 1980 using 1982, comment on the above statement is :

Q. (Base 1992 = 100) for the year 1993–97. The construction of chain index is :
During a certain period the cost of living index number goes up from 110 to 200 and the salary of a worker is also raised from Rs. 325 to Rs. 500. The worker does not get really gain. Then the real wages decreased by :
Firstly, we will calculate by how much the living index number increase, i.e.
200/110 = 1.818
Now, we'll multiply this factor by the wages before increase, so as to calculate the final increased wages for maintaining the right balance.
Rs 325 * 1.818 = Rs. 590.90
Hence, the real wages decrease by Rs.590.90  Rs.500 = Rs.90.90
Net monthly salary of an employee was Rs. 3000 in 1980. The consumer price index number in 1985 is 250 with 1980 as base year. If the has to be rightly compensated. Then 7th dearness allowances to be paid to the employee is :
Net Monthly income of an employee was Rs. 800 in 1980. The consumer price Index number was 160 in 1980. It is rises to 200 in 1984. If he has to be rightly compensated. The additional dearness allowance to be paid to the employee is :
When the cost of Tobacco was increased by 50%, a certain hardened smoker, who maintained his formal scale of consumption, said that the rise had increased his cost of living by 5%. Before the change in price, the percentage of his cost of living was due to buying Tobacco is
If the price index for the year, say 1960 be 110.3 and the price index for the year, say 1950 be 98.4. Then the purchasing power of money (Rupees) of 1950 will be of 1960 is
When index number is calculated for several variables, it is called:
⇒ When index number is calculated for several variables, it is called : Composite Index.
⇒ A composite index number is formed by combining two or more index numbers, and a weighting is usually given to each of the indexes in order to calculate the weighted average index number.
⇒ A composite index number is a number that measures an average relative change in a group of relative variables with respect to a base.
The consumer price Index for April 1985 was 125. The food price index was 120 and other items index was 135. The percentage of the total weight of the index is
The total value of retained imports into India in 1960 was Rs. 71.5 million per month. The corresponding total for 1967 was Rs. 87.6 million per month. The index of volume of retained imports in 1967 composed with 1960 (= 100) was 62.0. The price index for retained inputs for 1967 our 1960 as base is

If the 1970 index with base 1965 is 200 and 1965 index with base 1960 is 150, the index 1970 on base 1960 will be:
With regard to Laspeyre and Paasche price index numbers, it is maintained that If the Prices of all the goods change in the same ratio, the two indices will be equal for them the weighting system is irrelevant; or if the quantities of all the goods change in the same ratio, they will be equal, for them the two weighting systems are the same relatively. Then the above statements satisfy.
In 1996 the average price of a commodity was 20% more than in 1995 but 20% less than in 1994; and more over it was 50% more than in 1997 to price relatives using 1995 as base (1995 price relative 100) Reduce the data is:
Let say 1975 Price = 100
1976 price = 100 + (20/100)100 = 120
20% less than 1974 = 120
=> 1974 Price * ( 1  0.2) = 120
=> 1974 Price = 150
50% more than 1977 = 120
=> 1977 price * ( 1 + 0.5) = 120
=> 1977 price = 80
1974 = 150
1975 = 100
1976 = 120
1977 = 80
