Given the statement:
The population of a village was 6400. 3%population left the village and 5% died within a year.
Determine the population size after a year.
Solution:
Convert the percentages to decimal. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.
= 3/100
= 0.03
= 5/100
= 0.05
Take 3% and 5% of 6400 and subtract it to 6400.
= (6400) (0.03)
= 192
= (6400)(0.05)
= 320
=6400 -192 - 320
= 5,888
Final answer:
The population after a year is 5,888.
