Mettl Logical and Abstract Reasoning Questions and Answers — Questions and Answers
Question 1: In a certain code language, if 'SYSTEM' is coded as 'SYSMET', how is 'FRACTION' coded?
- CARFNOIT
- FRACNOIT (Correct answer)
- NOITCARF
- CARFTION
Correct answer: FRACNOIT
The logic is to interchange the last three letters. In 'SYSTEM', 'TEM' becomes 'MET'. Similarly, in 'FRACTION', the last three letters 'ION' become 'NOI', resulting in 'FRACNOIT'.
Question 2: Consider the following statements: 1. All scientists are researchers. 2. Some researchers are professors. Which of the following is a logically certain conclusion?
- All professors are scientists.
- Some scientists are professors.
- No scientist is a professor.
- No definite conclusion can be drawn between scientists and professors. (Correct answer)
Correct answer: No definite conclusion can be drawn between scientists and professors.
The statements establish that scientists are a subset of researchers, and there is an overlap between researchers and professors. However, the group of 'scientists' and the group of 'professors' could be entirely separate within the larger 'researcher' category. Therefore, we cannot definitively conclude anything about the relationship between scientists and professors.
Question 3: Find the missing number in the series: 5, 11, 24, 51, 106, ___
- 212
- 199
- 217 (Correct answer)
- 223
Correct answer: 217
The pattern is to multiply the current number by 2 and then add an incrementally increasing number, starting from 1. 5 * 2 + 1 = 11 11 * 2 + 2 = 24 24 * 2 + 3 = 51 51 * 2 + 4 = 106 106 * 2 + 5 = 217
Question 4: Which of the following pairs shares the same relationship as 'Odometer : Distance'?
- Scale : Weight (Correct answer)
- Thermometer : Illness
- Clock : Seconds
- Compass : Hiking
Correct answer: Scale : Weight
An odometer is an instrument used to measure distance. Similarly, a scale is an instrument used to measure weight. The other options are incorrect: a thermometer measures temperature (not illness), a clock measures time (seconds are a unit), and a compass indicates direction (hiking is an activity).
Question 5: A project manager is scheduling tasks. Task B must be done after Task A. Task C must be done before Task A. Task D must be done after Task B. Which of the following is a valid sequence for completing the tasks?
- A, C, B, D
- B, D, C, A
- C, A, D, B
- C, A, B, D (Correct answer)
Correct answer: C, A, B, D
The logical constraints are: C -> A -> B -> D. The only sequence that satisfies all these dependencies is C, A, B, D. C is before A, A is before B, and B is before D.
Question 6: Pointing to a man, a woman says, 'His mother is the only daughter of my mother.' How is the woman related to the man?
- Aunt
- Mother (Correct answer)
- Sister
- Grandmother
Correct answer: Mother
The 'only daughter of my mother' is the woman herself. Therefore, the statement simplifies to 'His mother is me'. This means the woman is the man's mother.
