The Correct Option is B
Solution and Explanation
From the graphs, the price change for each commodity can be calculated using the formula:
\[
\text{Price Change} = \frac{\text{Ending Price} - \text{Beginning Price}}{\text{Beginning Price}} \times 100
\]
By examining the price fluctuations, we can see that pepper experienced the highest price variation. Therefore, the Correct Answer is (2) Pepper.

Question: 2
Price Volatility (PV) of a commodity is defined as follows:
\[
PV = \frac{\text{Highest Price during the Period} - \text{Lowest Price during the Period}}{\text{Average Price during the Period}}
\]
What is the commodity with the lowest price volatility?
Price Volatility (PV) of a commodity is defined as follows:
\[
PV = \frac{\text{Highest Price during the Period} - \text{Lowest Price during the Period}}{\text{Average Price during the Period}}
\]
What is the commodity with the lowest price volatility?
Show Hint
In volatility calculations, look for commodities with a smaller range between the highest and lowest prices to identify the lowest price volatility.

The Correct Option is A
Solution and Explanation
To calculate price volatility, we examine the price fluctuations for each commodity. Arhar shows the least variation between its highest and lowest prices, resulting in the lowest volatility compared to other commodities. Therefore, the Correct Answer is (1) Arhar.

Show Hint
When calculating overall profit or loss, use a weighted average approach based on the percentage of investment in each commodity.

- 17% profit
- 5.5% loss
- No profit no loss
- 4.3% profit

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The profit or loss is calculated based on the weighted average of price changes for all four commodities. By examining the price fluctuations in each commodity, we find that Mr. X experienced a net profit of 4.3% on his total investment. Therefore, the Correct Answer is (4) 4.3% profit.

Question: 4
The price volatility of the commodity with the highest PV during the February-July period is approximately equal to:
The price volatility of the commodity with the highest PV during the February-July period is approximately equal to:
Show Hint
Price volatility can be estimated by looking at the highest and lowest points on the graph for each commodity.

- 3%
- 40%
- 20%
- 12%
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
To determine the price volatility (PV) for each commodity, we examine the price fluctuations from February to July. By using the formula for PV:
\[
PV = \frac{\text{Highest Price during the Period} - \text{Lowest Price during the Period}}{\text{Average Price during the Period}}
\]
The commodity with the highest price volatility shows a significant fluctuation in prices. Based on the graphs, the commodity with the highest PV is estimated to have a volatility of approximately 20%. Therefore, the Correct Answer is (3) 20%.

- The air-conditioner (AC) in a large room can be operated either in REGULAR mode or in POWER mode to reduce the temperature.
If the AC operates in REGULAR mode, then it brings down the temperature inside the room (called inside temperature) at a constant rate to the set temperature in 1 hour. If it operates in POWER mode, then this is achieved in 30 minutes.
If the AC is switched off, then the inside temperature rises at a constant rate so as to reach the temperature outside at the time of switching off in 1 hour.
The temperature outside has been falling at a constant rate from 7 pm onward until 3 am on a particular night. The following graph shows the inside temperature between 11 pm (23:00) and 2 am (2:00) that night.
The following facts are known about the AC operation that night.
The AC was turned on for the first time that night at 11 pm (23:00).
The AC setting was changed (including turning it on/off, and/or setting different temperatures) only at the beginning of the hour or at 30 minutes after the hour.
The AC was used in POWER mode for longer duration than in REGULAR mode during this 3-hour period.
