According to the given table, which of the following has the highest growth rate of production from 2001 to 2005?

Production of four elements (Thousand tonnes)

Correct option is B

Given:

The table provides the production data (in thousand tonnes) for four elements: Gold, Silver, Copper, and Iron, from the year 2001 to 2005.

Formula Used:

To calculate the growth rate, we use the formula:

​$$\text{Growth Rate} = \frac{\text{Production in 2005} - \text{Production in 2001}}{\text{Production in 2001}} \times 100$$​​

Solution:

The growth rate for Gold:

Growth Rate for Gold  = $$\frac{85 - 24}{24} \times 100 = \frac{61}{24} \times 100 \approx 254.17\%$$​​

The growth rate for Silver:

Growth Rate for Silver =$$\frac{103 - 87}{87} \times 100 = \frac{16}{87} \times 100 \approx 18.39\%$$​​

The growth rate for Copper:

Growth Rate for Copper = $$\frac{54 - 12}{12} \times 100 = \frac{42}{12} \times 100 \approx 350\%$$​​

The growth rate for Iron:

Growth Rate for Iron =$$\frac{69 - 27}{27} \times 100 = \frac{42}{27} \times 100 \approx 155.56\%$$​

Thus, Copper has the highest growth rate of approximately 350%.
