In this question a statement is given which is followed by two assumptions numbered I and II. You have to consider the statement and the following assumptions and decide which of the assumption (s) is/are implicit in the statement.

Statement: " X air-conditioner- the largest-selling name with the largest range" - an advertisement.

Assumptions:

I. X air-conditioner is the only one with wide variations.

II. There is a demand for air-conditioner in the market.

If only assumption II is implicit

Clearly, the advertisement does not mention the word 'only' i.e. other air-conditioners may also have wide variations. So, I is not implicit. Also, the advertisement is given so that the people know about that which they demand. So, II is implicit.
