Study the table carefully and answer the question based on it.

The below table shows the number of trees of 3 different fruits, planted during 2018-2022.

Year	Jackfruit	Mango	Butter Fruit
2018	35,000	40,000	55,000
2019	38,000	48,000	58,000
2020	42,000	52,000	62,000
2021	45,000	55,000	65,000
2022	48,000	58,000	68,000

What was the percentage increase in the number of mango trees planted in 2020 compared to the number of mango trees planted in 2018?

The correct answer is 30%.

To find the percentage increase in the number of mango trees planted in 2020 compared to 2018, we use the standard percentage increase formula:

\text{Percentage Increase}=\frac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\times 100

Step 1: Identify the values from the table.

From the table:
- Number of Mango trees planted in 2018 (Old Value) = 40,000
- Number of Mango trees planted in 2020 (New Value) = 52,000

Step 2: Calculate the increase.

Increase = New Value - Old Value
Increase = 52,000 - 40,000 = 12,000

Step 3: Apply the percentage increase formula.

\text{Percentage Increase}=\frac{\mathrm{12,000}}{\mathrm{40,000}}\times 100

\text{Percentage Increase}=\frac{12}{40}\times 100=0.30\times 100=30\%

Conclusion: The number of mango trees increased from 40,000 in 2018 to 52,000 in 2020, which is a rise of 12,000 trees. This represents a 30% increase.
