Logical Reasoning - Statement and Assumption

In each question below is given a statement followed by two assumptions numbered I and II. You have to consider the statement and the following assumptions and decide which of the assumptions is implicit in the statement.

Give answer

  • (A) If only assumption I is implicit
  • (B) If only assumption II is implicit
  • (C) If either I or II is implicit
  • (D) If neither I nor II is implicit
  • (E) If both I and II are implicit.

1. 

Statement: Sachin's mother instructed him to return home by train if it rains heavily.

Assumptions:

  1. Sachin may not be able to decide himself if it rains heavily.
  2. The trains may ply even if it rains heavily.

A. Only assumption I is implicit
B. Only assumption II is implicit
C. Either I or II is implicit
D. Neither I nor II is implicit
E. Both I and II are implicit

Answer: Option B

Explanation:

Sachin's mother has instructed him as a matter of caution and out of care for her child, and not because Sachin himself would not be able to decide. So, I is not implicit. Besides, Sachin's mother instructs him to take to train journey in case it rains heavily. So, II is implicit.

2. 

Statement: "Please put more people on the job to make up for the delay."

Assumptions:

  1. Delay is inevitable in most jobs.
  2. Output will increase with more number of people on the job.

A. Only assumption I is implicit
B. Only assumption II is implicit
C. Either I or II is implicit
D. Neither I nor II is implicit
E. Both I and II are implicit

Answer: Option B

Explanation:

The advice tells to 'make up for the delay' showing that delay is not to be done. So, I is not implicit. Since increase in number of people will make up for the delay, it means the output will increase with this increase in number. So, II is implicit.

3. 

Statement: In spite of less than normal rainfall in the catchment areas during the first two months of monsoon of the lakes supplying water to the city the authority has not yet affected any cut in the water supply to the city.

Assumptions:

  1. The rainfall during the remaining part of the monsoon may be adequate for normal water supply.
  2. The present water level of the lakes supplying water to the city may be adequate for normal supply.

A. Only assumption I is implicit
B. Only assumption II is implicit
C. Either I or II is implicit
D. Neither I nor II is implicit
E. Both I and II are implicit

Answer: Option E

Explanation:

The statement clearly indicates that at present the water level of the lakes is adequate. There is nothing of a shortage to induce a cut in water supply and still there is time to wait and watch the performance of rains during the remaining monsoon period. So, both I and II are implicit.

4. 

Statement: If you are an engineer, we have a challenging job for you.

Assumptions:

  1. We need an engineer.
  2. You are an engineer.

A. Only assumption I is implicit
B. Only assumption II is implicit
C. Either I or II is implicit
D. Neither I nor II is implicit
E. Both I and II are implicit

Answer: Option A

Explanation:

Clearly, job is offered to an engineer. This means that he is needed. So, I is implicit. The word 'If' in the statement makes II not implicit.

5. 

Statement: In spite of poor services, the commutators have not complained against it.

Assumptions:

  1. Generally people do not tolerate poor services.
  2. Complaints sometimes improve services.

A. Only assumption I is implicit
B. Only assumption II is implicit
C. Either I or II is implicit
D. Neither I nor II is implicit
E. Both I and II are implicit

Answer: Option A

Explanation:

The statement expresses an expectation of complaints from the people against poor services. So, I is implicit. But the effect of complaints cannot be deduced. So, II is not implicit.
