Which of the following assumptions is/are valid?

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 assumptions is/are valid?

  1. 1.Deflation strategies can be used to make manufacturers appear to be doing better than they actually are.
  2. 2.When input and output prices are both deflated against a single input price, it is referred to as ‘double deflation’.

Select the answer using the code given below.

Answer & explanation

Answer: (a) 1 only

The passage shows that using one deflator for inputs and outputs can make a manufacturer look more productive than it is, so the choice of deflation method can flatter performance. Statement 2 inverts the definition: double deflation deflates input and output prices separately.

  • ✓ 1. With a single deflator 'it would look as if the manufacturer had become more productive' — the method of deflation can make performance look better than it is.
  • ✗ 2. Double deflation is where 'input and output prices are deflated separately'; using a single deflator is the Indian practice the passage criticises.

Remember · Definition-based statements: check the definition in the passage exactly; a reversed definition is always invalid.
