Question

during one year the poplulation of a village increased by 5% and during the next year it diminished by 5% if at the end of the second year the population was 798 what was it at the beginning of the first year​​

Answer 1

Answer:

800

Step-by-step explanation:

Let's assume the population is 100%

By a increase of 5% it becomes 105%

Now population decrease of 5% is a decrease on total 105% so it becomes,

105- ((5*105)/100)= 99.75

Now 99.75% is 798 people, then 100% is,

(100*798)/99.75 = 800
