💡 Analysis & Explanation
Column Isolation ▼
We need to focus exclusively on the vertical column labeled 'Leisure' to capture data across all provided years.
Summing the Values ▼
The sequential spending points are 5, 6.5, 7.3, 7.9, and 8.5. Adding these values together yields a total sum of 35.2.
Average Formula Calculation ▼
The statistical average is derived by dividing the total sum by the number of data points (5 years). 35.2 / 5 = 7.04.
Unit Adjustment ▼
Since the table is denominated in 'Thousand Rupees', we must multiply the raw average by 1,000. 7.04 * 1000 = 7040.
Conclusion ▼
The mathematically correct annual average is Rs. 7,040.
