Question

The population of a town was 59000. In one year, it was increased by 4536 due to new births. However, 9218 persons died or left the town during the year. What was the population at the end of the year?

Answer 1

Hint:
To find the population at the end of the year, first we will add the increased population of the town to the given population of the town and then we will subtract the decreased population from it.

Complete step by step solution:
Given,
The population of the town was 59000.
The population increased due to new birth in one year is 4536.
The population decreased during the year due to deaths or people leaving the town is 9218.
Therefore, the population at the end of the year is given by
The population of the town + The population increased due to new birth - The population decreased due to deaths and migration
 \[59000 + 4536-9218 = 54318\]

Therefore, there were 54318 people at the end of the year.

Note:
The population of the town is decreased because the birth rate of the town is less than the death rate of the town. If death rate exceeds birth rate, the population decreases. Also, if birth rate is greater than death rate then population increases (i.e. if birth rate exceeds death rate, the population grows).
