Analyzing IT Job Vacancy Trends in Hyderabad (2009-2019)

The question asks us to find the approximate percentage rise in IT job vacancies in the city of Hyderabad between the years 2009 and 2019. To solve this, we need to use the data provided in the table regarding the percentage distribution of vacancies and the total number of vacancies in each year.

Understanding the Provided Job Vacancy Data

The table shows the percentage of total IT job vacancies located in different Indian cities for the years 2009 and 2019. We are also given the total number of vacancies for each of these years.

Total vacancies in 2009 = 5.4 lakhs

Total vacancies in 2019 = 8.6 lakhs

Calculating Vacancies in Hyderabad for Each Year

First, we need to calculate the actual number of job vacancies in Hyderabad for both 2009 and 2019 using the percentages and the total vacancies.

Vacancies in Hyderabad in 2009:

• Percentage of vacancies in Hyderabad in 2009 = 10%
• Total vacancies in 2009 = 5.4 lakhs
• Number of vacancies in Hyderabad in 2009 = 10% of 5.4 lakhs
• Using the formula: $\text{Value} = \frac{\text{Percentage}}{100} \times \text{Total}$
• Vacancies in Hyderabad (2009) = $\frac{10}{100} \times 5.4 \text{ lakhs} = 0.1 \times 5.4 \text{ lakhs} = 0.54 \text{ lakhs}$

Vacancies in Hyderabad in 2019:

• Percentage of vacancies in Hyderabad in 2019 = 8%
• Total vacancies in 2019 = 8.6 lakhs
• Number of vacancies in Hyderabad in 2019 = 8% of 8.6 lakhs
• Vacancies in Hyderabad (2019) = $\frac{8}{100} \times 8.6 \text{ lakhs} = 0.08 \times 8.6 \text{ lakhs} = 0.688 \text{ lakhs}$

Calculating the Percentage Rise in Vacancies

Now that we have the number of vacancies in Hyderabad for both years, we can calculate the rise in vacancies and then the percentage rise. The formula for percentage rise is:

$\text{Percentage Rise} = \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \times 100$

In this case, the Original Value is the number of vacancies in 2009, and the New Value is the number of vacancies in 2019.

• Original Value (Vacancies in 2009) = 0.54 lakhs
• New Value (Vacancies in 2019) = 0.688 lakhs
• Rise in vacancies = Vacancies in 2019 - Vacancies in 2009
• Rise in vacancies = $0.688 \text{ lakhs} - 0.54 \text{ lakhs} = 0.148 \text{ lakhs}$
• Percentage Rise = $\frac{0.148}{0.54} \times 100$
• Percentage Rise = $\frac{148}{540} \times 100 = \frac{1480}{54}$
• Percentage Rise $\approx 27.4074...$

The approximate percentage rise seen in vacancies available in the city of Hyderabad from 2009 to 2019 is 27.41%.

Conclusion on Hyderabad Vacancy Rise

Based on our calculations, the approximate percentage increase in IT job vacancies in Hyderabad between 2009 and 2019 is 27.41%.

Additional Information: Understanding Percentage Change

Percentage change is a way to express how much a value has increased or decreased compared to its original value. It is commonly used to analyze trends over time, such as changes in prices, populations, or, as in this case, job vacancies.

The general formula is:

$\text{Percentage Change} = \frac{\text{Change in Value}}{\text{Original Value}} \times 100$

If the change is an increase (New Value > Original Value), the result is a positive percentage rise. If the change is a decrease (New Value < Original Value), the result is a negative percentage change, often referred to as a percentage drop or decrease.

In this problem, we specifically calculated the percentage rise because the number of vacancies in Hyderabad increased from 0.54 lakhs to 0.688 lakhs.
