Answer:

the birth rate is 7.5 %

number of population birth in a year =

7.5/100 X 600000

= 45000

so in one and half year after

45000+ 22500

= 67500

similarly number of people dead in one year =

4.5/100 X 600000

27000

so in one and half year after

27000 + 13500

= 40500

the number of people if town

600000 + ( 67500 - 40500)

62700

the population of town after 1 and half year is equal to 62700

hope this answer will help you
