Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
To compare two sum totals as a percentage increase or decrease, we calculate the absolute difference between the sums and express it as a percentage of the reference sum (Veer's total salary).
Key Formula or Approach:
The percentage difference is calculated as:
\[ \text{Percentage Difference} = \frac{\text{Jai's Total} - \text{Veer's Total}}{\text{Veer's Total}} \times 100 \]

Step 2: Detailed Explanation:
Let us extract and sum the values for the specified years (2016, 2019, and 2020):
1. Total Salary of Jai (Jay):
- In 2016 = 40 thousand
- In 2019 = 60 thousand
- In 2020 = 80 thousand
\[ \text{Jai's Total} = 40 + 60 + 80 = 180\text{ thousand} \]
2. Total Salary of Veer:
- In 2016 = 60 thousand
- In 2019 = 40 thousand
- In 2020 = 60 thousand
\[ \text{Veer's Total} = 60 + 40 + 60 = 160\text{ thousand} \]
3. Compare the totals:
Since Jai's total ($180$) is greater than Veer's total ($160$), we calculate the percentage by which it is more:
\[ \text{Difference} = 180 - 160 = 20\text{ thousand} \]
\[ \text{Percentage More} = \frac{20}{160} \times 100 \]
\[ \text{Percentage More} = \frac{1}{8} \times 100 = 12.5\% \]
This matches Option A.

Step 3: Final Answer:
Jai's total salary is 12.5% more than Veer's.
