The correct answer is

1.98 lakh

  To find the total number of job vacancies available in Chennai in 2010 and in Mumbai in 2020, we need to use the percentage distribution provided in the table and calculate based on the total vacancies for the respective years.

  1. Identify the Total Number of Vacancies:
    In the problem, it is given that the total number of job vacancies in all the cities in 2010 is 5.4 lakh and in 2020 is 8.6 lakh.
  2. Calculate Chennai's Vacancies in 2010:
    The percentage of job vacancies in Chennai in 2010 is 8%. Thus, the number of vacancies in Chennai for 2010 can be calculated as follows: 
\[\text{Vacancies in Chennai, 2010} = \frac{8}{100} \times 5.4 \, \text{lakh} = 0.432 \, \text{lakh}\]
  1. Calculate Mumbai's Vacancies in 2020:
    The percentage of job vacancies in Mumbai in 2020 is 18%. Thus, the number of vacancies in Mumbai for 2020 can be calculated as follows: 
\[\text{Vacancies in Mumbai, 2020} = \frac{18}{100} \times 8.6 \, \text{lakh} = 1.548 \, \text{lakh}\]
  1. Add the Vacancies in Chennai (2010) and Mumbai (2020):
    Now, add the calculated vacancies from the two cities and years to get the total: 
\[\text{Total Vacancies} = 0.432 \, \text{lakh} + 1.548 \, \text{lakh} = 1.98 \, \text{lakh}\]

Conclusion:
The total number of job vacancies available in Chennai in 2010 and in Mumbai in 2020 is 1.98 lakh.

The correct answer is: 1.98 lakh
