​

Answer 1

Answer:

100 + 15 = 115 . So, population of first year is 115.

Answer 2

$ANSWER$

Answer : 2.25%

Explanation -

Let the population = 100

First year, it's increased by 15%

100 x 15/100 = 15

100 + 15 = 115 .

So, population of first year is 115.

Second year, it's decreased by 15%

115 x 15/100 = 17.25

115 - 17.25 = 97.75

So, population of second year is 97.75

Finding the Net decrease -

100 - 97.75 = 2.25

Net decrease = 2.25

Finding the percentage of Net decrease -

Percentage = (Net decrease/initial value) x 100

Percentage = (2.25/100) x 100

Percentage = 2.25%

Hence :

Answer:2.25%
