Increase% = (4500/18000 x 100)% = 25%

Required average = (25/10)% = 2. 5%

Answer 2

Answer:

⇒ The average percentage increase of population per year of that village is 2.5%

Step-by-step explanation:

Given data

⇒ the total population of a village increased from 18000 to 22500 in a decade   [ decade means 10 years ]

⇒ here we need to find the average percentage of increased population per year

⇒ the increased population = 22500 - 18000 = 4500

⇒ the percentage of the increased population = $\frac{4500}{18000} ( 100)$  

                                                                              = $\frac{450}{18} = 25%$  

⇒ the average percentage per year = 25/ 10 = 2.5 %  

⇒ The average percentage increase of population per year of that village is 2.5%
