Answer 1

Answer:

Step-by-step explanation:

A + B + AB/100

First two years, net increase.

10 + 10 + (10x10)/100 = 21%

Again,

Next two years, net decrease.

-10 -10 + 100/100 = -19%

Finally combined effect :

21 - 19 + (21 x -19)/100

= -1.99%

Net decrease after 4 years is 1.99%

Net population after 4 years is :

1,00,000 x 98.01% = 98010
