Question

the population of a town was 16000 three years ago. If it had increased by 3%,2.5% and 5% in the last three years, find the present population of the town

Answer 1

Step-by-step explanation:

initial population =16000

by next year it increased by 3% so initial population + 3%of her initial salary = 16000 + 3% × 16000

= 16000 + 480

= 16480

next year again it increased by 2.5% so, = 16480 + 2.5% × 16480

= 16480 + 412

= 16892

next year again it increased by 5% so, = 16892 + 5% × 16982

= 16892 + 849.1

= 17741.1

therefore, the present population is 17741.1
