What is the difference between the number of job vacancies available in Bangalore in the years 2020 and 2010 ?
108200
To find the difference in the number of job vacancies in Bangalore between 2020 and 2010, we need to calculate the actual number of vacancies for both years and then find the difference.
- First, calculate the vacancies in Bangalore for the year 2010:
- Total vacancies in 2010 = 5.4 lakhs = \(540,000\)
- Bangalore's percentage in 2010 = 15%
- Vacancies in Bangalore (2010) = \(540,000 \times \frac{15}{100} = 81,000\)
- Next, calculate the vacancies in Bangalore for the year 2020:
- Total vacancies in 2020 = 8.6 lakhs = \(860,000\)
- Bangalore's percentage in 2020 = 22%
- Vacancies in Bangalore (2020) = \(860,000 \times \frac{22}{100} = 189,200\)
- Now, find the difference in the number of vacancies between the two years:
- Difference = Vacancies in Bangalore (2020) - Vacancies in Bangalore (2010)
- Difference = \(189,200 - 81,000 = 108,200\)
Therefore, the difference in the number of job vacancies available in Bangalore between the years 2020 and 2010 is 108,200.
