Answer:
The change in the standard of living, measured by growth in real GDP per person, is 0.1356%
Step-by-step explanation:
Given,
In the current year,
Population = 31.5 million,
Real GDP = $814 million,
So, the real GDP per person =
≈ 25.841
In the previous year,
Population = 31 million,
Real GDP = $800 million,
So, the real GDP per person =
≈ 25.806
Hence, change percentage = 



≈ 0.1356 %
This is a simple problem based on combinatorics which can be easily tackled by using inclusion-exclusion principle.
We are asked to find number of positive integers less than 1,000,000 that are not divisible by 6 or 4.
let n be the number of positive integers.
∴ 1≤n≤999,999
Let c₁ be the set of numbers divisible by 6 and c₂ be the set of numbers divisible by 4.
Let N(c₁) be the number of elements in set c₁ and N(c₂) be the number of elements in set c₂.
∴N(c₁) =

N(c₂) =

∴N(c₁c₂) =

∴ Number of positive integers that are not divisible by 4 or 6,
N(c₁`c₂`) = 999,999 - (166666+250000) + 41667 = 625000
Therefore, 625000 integers are not divisible by 6 or 4
