Answer 1

Answer:

Step-by-step explanation:

Population of the village 2 years ago was16000.

It increased at the rate of 10%

Polulation the next year= P(1+ R/100)n

=16000 (1+ 10/100)

=16000 (11/10)

=17600

Therefore, the polulation is 17600.

The next year it decreased by 18% .

The population now =P(1- R/100)n

=17600 (1-18/100)

=17600 (1 - 9/50)

= 17600 (41/50)

=14432

The population now is 14,432.
