Answer 2

Given,

The population of a state increased by 9%, 16% respectively from 2012 to 2013.

To find,

The average increase over these years

Solution,

The average is equal to the sum of all the values divided by the total number of values.

The formula is given below:

Average= Total sum of values/Total number of values

Putting the values in the above formula:

The average increase of population over these years = (9% + 16%)/2

The average increase of population over these years = 25%/2

The average increase of population over these years = 12.5%

Hence, the average increase of population over 2012 and 2013 is 12.5%
