Which of the following statements is/are correct?

Directions for the next 2 (two) items: Read the following passage and answer the items that follow. Your answers should be based solely on the passage.

Passage

How is deflation done? Most countries use a method called ‘double deflation’, where input and output prices are deflated separately. Consider a manufacturer importing oil for use in production. If oil prices fall, output prices do not and quantities remain the same, real value added should not change. But if the same deflator is used for inputs and outputs, as in India, it would look as if the manufacturer had become more productive.

Which of the following statements is/are correct?

  1. 1.Real value should not change in the instance of static output cost and unchanged quantities against falling oil prices.
  2. 2.Deflators are to be used separately for inputs and outputs, and this is a practice universally adopted by all economies.

Select the answer using the code given below.

Answer & explanation

Answer: (d) Neither 1 nor 2

Statement 1 looks like a paraphrase but changes two terms: the passage holds output prices (not output cost) steady and speaks of real value added (not real value). Statement 2 turns 'most countries' into 'all economies', which India itself contradicts.

  • ✗ 1. The passage's example keeps output prices unchanged while oil (an input) gets cheaper — so the cost of producing output actually falls. It says real value added, not 'real value', stays the same. The statement misstates both terms.
  • ✗ 2. The passage says 'Most countries' use double deflation and notes India uses the same deflator for inputs and outputs, so it is not universal.

Remember · Compare near-copy statements word by word; 'price' vs 'cost' and 'most' vs 'all' decide such items.
