[N.A.B.A.R.D. (PO) 2010]

Question : 1

  • Statement:
  • A leading university has begun a practice of displaying results only on the Internet rather than on the main notice boards.
  • Assumptions:
  • I. All the students enrolled in the university have access to the Internet at home.
  • II. Most of the students referred to the result displayed on both the internet as well as the notice boards earlier.

a) If only Assumption I is implicit

b) If only Assumption II is implicit

c) If either Assumption I or II is implicit

d) If neither Assumption I nor II is implicit

e) If both Assumptions I and II are implicit

Answer: (d)

Assumption I is invalid as the assumption is that the students have access to the internet. But it is not necessary that they have this access at home.

Further, the past practice may not have been borne in mind while switching over to internet only display.

Hence, Assumption II is also invalid.

Question : 2

  • Statement:
  • In order to replenish the nutrients in the soil, it is important to grow different types of crops every alternate season.
  • Assumptions:
  • I. A crop can never be grown for the second time in the same field.
  • II. If a different crop is grown in the successive season, no additional nutrients such as fertilizers are required to be added to the soil.

a) If only Assumption I is implicit

b) If only Assumption II is implicit

c) If either Assumption I or II is implicit

d) If neither Assumption I nor II is implicit

e) If both Assumptions I and II are implicit

Answer: (d)

Assumption I is not implicit as it has no connection with the given statement. The need to grow different types of crops is talked about precisely because there is a likelihood of farmers growing the same crop again and again unless instructed.

Further, growing different types of crops is important but not sufficient.

Therefore, Assumption II is also not valid.

Question : 3

  • Statement:
  • If farmers want to improve their yield, they must use organic fertilizers in place of chemical fertilizers.
  • Assumptions:
  • I. Chemical fertilizers have certain ill effects on health.
  • II. Chemical fertilizers do not produce as much yield as organic fertilizers.

a) If only Assumption I is implicit

b) If only Assumption II is implicit

c) If either Assumption I or II is implicit

d) If neither Assumption I nor II is implicit

e) If both Assumptions I and II are implicit

Answer: (b)

Assumption I is invalid as the given statement does not focus on health. The sentence 'If farmers want to improve their yield’ proves that Assumption II is hidden in the given statement because the word ‘improve’ itself hints towards the increase of production.

Hence, Assumption II is implicit.

Question : 4

  • Statement:
  • Store eatables in the deep freeze in order to preserve these for a long time.
  • Assumptions:
  • I. Food material remains eatable even after deep freezing for a long time.
  • II. It is not possible to store any eatable at room temperature even for a shorter period of time.

a) If only Assumption I is implicit

b) If only Assumption II is implicit

c) If either Assumption I or II is implicit

d) If neither Assumption I nor II is implicit

e) If both Assumptions I and II are implicit

Answer: (a)

Assumption I must be valid because only then does the storage make sense. Further, the statement has nothing to do with “a shorter period of time".

Hence, Assumption II is invalid.

Question : 5

  • Statement:
  • A leading NGO decided to open a library containing books and newspapers of all major publishers in a remote village.
  • Assumptions:
  • I. All other nearby villages already have similar libraries.
  • II. There is an adequate number of literate people in the village.

a) If only Assumption I is implicit

b) If only Assumption II is implicit

c) If either Assumption I or II is implicit

d) If neither Assumption I nor II is implicit

e) If both Assumptions I and II are implicit

Answer: (b)

Assumption I is not implicit as it has no relation with the given statement. The statement does not give any information about other villages.

Further literacy is necessary for a library to be successful.

Hence, II is implicit.
