Text Solution

Verified by Experts

The correct Answer is:
C

In 2016 the population would be `=12483xx2=24996`
In 2023 the population would be
`=24996xx2=49932`
In 2030 the population would be
`=49932xx2=99864`
Therefore, increase in population by 2030
99864 - 12483 = 87381
Increase in population by 2023 = 49932 - 12483 = 37449
Thus, the required year would be after 2023 and before 2030.
