Step 1: Understanding the Concept:
To find the total earnings of the farmer over a specific time period, we must calculate the total quantities of both crops produced during those years and multiply them by their respective contract selling prices.
Key Formula or Approach:
- Total Earning = \((\text{Total Castor} \times 45) + (\text{Total Cotton} \times 40)\)
- Note: The time period is 2011 to 2016 (excluding 2017).
Step 2: Detailed Explanation:
Let us extract the values from the chart for the years 2011 to 2016:
- Castor Production (Kgs):
- 2011: 290, 2012: 230, 2013: 340, 2014: 220, 2015: 190, 2016: 180.
\[ \text{Total Castor} = 290 + 230 + 340 + 220 + 190 + 180 = 1450\text{ Kgs} \]
- Cotton Production (Kgs):
- 2011: 330, 2012: 230, 2013: 280, 2014: 200, 2015: 320, 2016: 140.
\[ \text{Total Cotton} = 330 + 230 + 280 + 200 + 320 + 140 = 1500\text{ Kgs} \]
- Calculating total earnings:
\[ \text{Earning from Castor} = 1450 \times 45 = 65250\text{ Rs} \]
\[ \text{Earning from Cotton} = 1500 \times 40 = 60000\text{ Rs} \]
\[ \text{Total Earning} = 65250 + 60000 = 125250\text{ Rs} \]
Step 3: Final Answer:
The total earning of the farmer for the period 2011 to 2016 is Rs. 125250 (Option A).
