If the average level of nominal income in a nation is $21,000 and the price level index is 154, the average real income is about:-

a)$12,546 b)$13,636 c)$15,299 d)$17,823

real income= avglevel/priceindex

$13636

$13,636

To calculate the average real income, we need to divide the average nominal income by the price level index.

The formula to calculate real income is:

Real Income = Nominal Income / Price Level Index

Let's plug in the values given:

Average nominal income = $21,000
Price level index = 154

Real Income = $21,000 / 154

Calculating this, we get:

Real Income ≈ $136.36

To convert this to an annual average real income, we multiply by 12, assuming a 12-month period:

Annual Average Real Income ≈ $136.36 × 12

Annual Average Real Income ≈ $1,636.36

Rounded to the nearest dollar, the average real income is approximately $1,636.

Therefore, the correct answer is (b) $13,636.
