C Correct answer
Explanation

$\Rightarrow$  When the prices of rice are to be compared, we compute: $Price\,Index.$

$\Rightarrow$  Price index, measure of relative price changes, consisting of a series of numbers arranged so that a comparison between the values for any two periods or places will show the average change in prices between periods or the average difference in prices between places. 
$\Rightarrow$  In most countries price indexes are used to measure inflation, each focusing on the prices of a collection of goods and services important to a particular segment of the economy.

Price relatives computed by chain base method are called: 

  1. Price relatives

  2. Chain indices

  3. Link relatives

  4. None of them
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

$\Rightarrow$  Price relatives computed by chain base method are called $Link\,\,relatives.$

$\Rightarrow$  Under this method, the base year’s price does not remain fixed but moves step from year to year. In other words, the immediately preceding year’s price becomes the base year’s price for each of the succeeding years.
$\Rightarrow$  Under this method, the base year’s price does not remain fixed but moves step from year to year. In other words, the immediately preceding year’s price becomes the base year’s price for each of the succeeding years.

$\Rightarrow$  $Chain\, index$ = $\dfrac{Average\, link\, relative\, of\, current\, year \times Chain\, index\, of\, previous\, year}{100}$

Consumer price index are obtained by:

  1. Paasche's formula

  2. Fisher's ideal formula

  3. Marshall Edgeworth formula

  4. Family budget method formula
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

$\Rightarrow$  Consumer price index are obtained by: $Family\,\,budget\,\,method\,\,formula.$

$\Rightarrow$  In this method, the family budgets of a large number of people are carefully studied and the aggregate expenditure of the average family for various items is estimated. 
$\Rightarrow$  These values are used as weights. The current year’s prices are converted into price relatives on the basis of the base year’s prices, and these price relatives are multiplied by the respective values of the commodities in the base year. The total of these products is divided by the sum of the weights and the resulting figure is the required index numbers.
$P _{0n}=\dfrac{\sum WI}{\sum W}$   Here, $I=\dfrac{P _n}{P _0}\times 100$  and $W=P _0q _0$

Commodity A B C D E
Price in 1990 100 80 160 220 40
Price in1991 140 120 180 240 40

  2. 130.14

  3. 114.56

  4. 124.53
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
 $Commodity$ $Price\,in\,1991$$P _0$  $Price\,in\,1991$$P _1$  $Price\,relative$$\dfrac{P _1}{P _0}\times 100$ 
 $A$ $100$  $140$  $140$ 
$B$  $80$  $120$  $150$
$C$  $160$  $180$  $112.5$
$D$  $220$  $240$  $109.09$
$E$  $40$  $40$  $100$ 
 $Total$     $611.59$

$\therefore$   By using simple average of price relative method,

$\Rightarrow$   $P _{01}=\dfrac{\sum P _{01}}{N}=\dfrac{611.59}{5}=122.32$
