RBI OFFICER GRADE ‘B’ PHASE-I EXAM Held on : 09.11.2019(Part-I)

Total Questions: 50

41. Study the following information carefully and answer the question given below :

High amount of 'trinium' blocks the absorption of 'roassium' by the plants thererby crippling them. Thus, in village R, the yield of jute is adversely affected. In order to address this situation the use of groundwater for irrigation should be completely stopped in the village.
Which of the following statements can be concluded from the given information?
(A) Jute plants need roassium in order to grow well.
(B) The groundwater in village R contains high amount of 'trinium'
(C) The groundwater in village R contains 'roassium' to atleast some extent.
(D) For the jute crop to grow well, the concentration of 'trinium' in the soil should essentially be zero.

Correct Answer: (3) Both (A) and (B)
Solution:Only (A) and (B) can be concluded from the given information. The first line implies that jute plants need roassium in order to grow well. In order to address the problem of trinium, the use of groundwater for irrigation be stopped completely. It implies that the groundwater in village R contains high amount of trinium. The source of roassium may be other than groundwater. Therefore, statement (C) does not follow.
It is mentioned in the very first line that high amount of ‘trinium’ blocks the absorption of ‘roassium’.
Therefore, statement (D) does not follow.

42. Each of the questions below consists of some statements followed by three Conclusions numbered I, II and III. Consider the given statements to be true even if they seem to be at variance with commonly known facts. Read all the Conclusions and then decide which of the given Conclusions follow(s) logically from the given statements.

Statements :
All heights are peaks.
No height is a mountain.
All mountains are landscapes.
Only a few mountains are valleys.
Conclusions:
I. Some valleys being heights is a possibility.
II. No peak is a landscape.
III. Atleast some valleys are landscapes.

Correct Answer: (2) Both I and III follow
Solution:

(i) All heights are peaks → Universal Affirmative (A–type).
(ii) Only a few mountains are valleys → Particular Affirmative (I–type).
[Only a few = Some]
(iii) No height is a mountain → Universal Negative (E–type).
(iv) Some heights are not mountains → Particular Negative (O–type).





Venn diagrams I and II support the Conclusion I.
Thus, Conclusion I and Conclusion III follow.

43. Each of the questions below consists of some statements followed by three Conclusions numbered I, II and III. Consider the given statements to be true even if they seem to be at variance with commonly known facts. Read all the Conclusions and then decide which of the given Conclusions follow(s) logically from the given statements.

Statements :
Only a few books are tables.
All tables are novels.
Only a few tables are chairs.
All chairs are drawers.
Conclusions :
I. Some chairs are definitely not books.
II. All novels being chairs is a possibility.
III. All tables are drawers.

Correct Answer: (3) Only II follows
Solution:

(i) All heights are peaks → Universal Affirmative (A–type).
(ii) Only a few mountains are valleys → Particular Affirmative (I–type).
[Only a few = Some]
(iii) No height is a mountain → Universal Negative (E–type).
(iv) Some heights are not mountains → Particular Negative (O–type).



Venn diagrams of " Some chairs are novels".


After combining venn diagrams II and VI, we get :

Venn diagram VII contradicts the Conclusion I.
Venn diagram V supports the Conclusion II.

44. Each of the questions below consists of some statements followed by three Conclusions numbered I, II and III. Consider the given statements to be true even if they seem to be at variance with commonly known facts. Read all the Conclusions and then decide which of the given Conclusions follow(s) logically from the given statements.

Statements :
No choice is an option.
Only a few options are alter- natives.
All alternatives are plans.
No alternative is a goal.
Conclusions:
I. All goals being choices is a possibility.
II. Atleast some options are plans.
II. All choices can never be alternatives.

Correct Answer: (3) Only III follows
Solution:

(i) All heights are peaks → Universal Affirmative (A–type).
(ii) Only a few mountains are valleys → Particular Affirmative (I–type).
[Only a few = Some]
(iii) No height is a mountain → Universal Negative (E–type).
(iv) Some heights are not mountains → Particular Negative (O–type).
