Answer 1

Answer:

the population will be 162000 after 2 years

Step-by-step explanation:

=> 150000 x 4/100

=> 1500 x 4

=> 6000 x 2

=> 12000

therefore the overall population after 2 years will be 162000

Answer 2

Answer:

162240

Step-by-step explanation:

present population (p): 150000

rate of growth of population per year (r): 4%

time interval (n): 2 years

according to the question,

population after 2 years = p(1+r/100)^n

= 150000(1+4/100)^2

= 150000(1+1/25)^2

= 150000(26/25)^2

= 150000 × 26/25 × 26/25

= 162240 (ans)
