This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
195000

The question asks for the new total population of Goa after a specific group of people migrates from Delhi to Goa. We need to calculate the number of migrants and add it to Goa's current population using the data provided in the table.

Table Data Extraction

From the table, we extract the following key information:

  • Original total population of Goa = 175000
  • Population of the 18-25 years age-group in Delhi = 80000

Migration Calculation

The number of people moving from Delhi to Goa is 25% of the 18-25 years age-group population in Delhi.

Number of migrants = 25% of 80000

Number of migrants = $0.25 \times 80000$

Number of migrants = $20000$

Goa's New Population Calculation

The new total population of Goa is its original population plus the migrants from Delhi.

New population of Goa = Original population of Goa + Number of migrants

New population of Goa = $175000 + 20000$

New population of Goa = $195000$

Final Answer

The total population of Goa will be 195000 after the migration.
