SSC CGL National Income Mock Test 2026: 50 MCQs with Detailed Answers

National Income becomes confusing when GDP, GNP, NDP and NNP start appearing together. The formulas are not very difficult, but one word such as gross, net, domestic or national can completely change the calculation.

Quick Formula Notebook

GDP to NDP NDP = GDP - Depreciation

GDP to GNP GNP = GDP + Net Factor Income from Abroad

GNP to NNP NNP = GNP - Depreciation

GDP Deflator Nominal GDP / Real GDP x 100

Per Capita Income National Income / Population

National Income is one of those topics where students often know the full forms but still make mistakes in the question. GDP and GNP may look almost the same, while NDP and NNP become confusing because both involve depreciation.

The easiest way to solve these questions is to read every word separately. Domestic tells you where the production happened. National tells you whose factor income is being considered. Gross means depreciation is still included, while Net means depreciation has been removed.

This mock test gives you direct concept questions as well as small calculation and inclusion-exclusion questions. The goal is not to memorise fifty answers. The goal is to make the formula clear enough that you can handle a slightly changed question in the exam.

Most common confusion

Domestic and National are not the same thing.

GDP is connected with production inside domestic territory. GNP or GNI adjusts the domestic measure using net factor income from abroad.

Gross to Net Subtract depreciation.

Domestic to National Adjust using net factor income from abroad.

Nominal to Real Remove the effect of price change.

Avoid Double Counting Count final output or value added, not both intermediate and final value.
