Match List I with List II
Choose the correct answer from the options given below:
| List I | List II |
| A. Quantity index | I. Measures relative price change over a period of time. |
| B. Time series | II. Measures change in quantity of consumption of goods over a specific period of time. |
| C. Price index | III. Measures average value of goods for specific time period. |
| D. Value index | IV. Statistical observation taken at different points of time for specific period of time. |
1
2
3
4
Solution
Quantity index → Measures change in quantity over time
So A → II
Time series → Statistical observations at different time points
So B → IV
Price index → Measures relative price change over time
So C → I
Value index → Measures average value for specific time period
So D → III
Correct matching:
A-II, B-IV, C-I, D-III
Given that
$\sum p_0 q_0 = 700$,
$\sum p_0 q_1 = 1450$,
$\sum p_1 q_0 = 855$,
$\sum p_1 q_1 = 1300$.
Where subscripts $0$ and $1$ are used for base year and current year respectively.
The Laspeyres’ price index number is:
1
2
3
4
Solution
Laspeyres price index:
$L=\frac{\sum p_1 q_0}{\sum p_0 q_0}\times 100$
Substitute values:
$L=\frac{855}{700}\times 100$
$=1.2214\times 100$
$=122.14$
One of the following is true for relation between sample mean $\bar{x}$ and population mean $\mu$.
1
2
3
4
Solution
By Law of Large Numbers, as sample size increases, sample mean $\bar{x}$ approaches population mean $\mu$.
Therefore,
$|\bar{x}-\mu|$ decreases as sample size increases.
Below are the stages for Drawing statistical inferences.
A. Sample
B. Population
C. Making Inference
D. Data tabulation
E. Data Analysis
Choose the correct answer from the options given below:
1
2
3
4
Solution
Correct logical order:
Population → Sample → Data tabulation → Data Analysis → Making Inference
So sequence:
B → A → D → E → C
Sitaram, a money lender lent a part of Rs. $200000$ to Shyam at simple interest $6%$ p.a. and the remaining to Sushil at $10%$ p.a. at simple interest.
Sitaram earned an annual interest income of Rs. $18000$.
What is the mean rate of interest?
1

4
Solution
Total principal = Rs. $200000$
Total annual interest earned = Rs. $18000$
Mean rate of interest:
$\text{Mean Rate}=\frac{\text{Total Interest}}{\text{Total Principal}}\times 100$
$=\frac{18000}{200000}\times 100$
$=0.09\times 100$
$=9%$
