the number of deer decreases at the rate of 8% per annum. What will be population
of deer in the year 2017?

Answer 1

Answer:

The population of deer in the year 2017 is 21160.

Step-by-step explanation:

Given that the population of deer in 2015 is 25000. The number decreases at the rate of 8% per annum. The 8% of 25000 is,

$\dfrac{8}{100} \times 25000=2000$

So the number of deer decreases by 2000. Thus the number of deer in 2016 is,

$25000-2000=23000$

Again, in the next year, the count decrease by 8%. So 8% of 23000 is

$\dfrac{8}{100}\times 23000=1840$

So the count decrease by 1840 again. So the number of deer in 2017 is

$23000-1840=21160$
