NTSE Mental Ability & Reasoning — Questions and Answers
Question 1: If A is the father of B, but B is not the son of A, what is B to A?
- Daughter (Correct answer)
- Son
- Cousin
- Mother
Correct answer: Daughter
This is a logical deduction riddle. If A is the father of B, then B is A's child. The statement explicitly says B is not the son of A. Therefore, if B is A's child and not male, B must be female. Thus, B is A's daughter.
Question 2: What comes next in the sequence: 2, 6, 12, 20, 30, ?
- 42 (Correct answer)
- 40
- 44
- 46
Correct answer: 42
This sequence follows a pattern where the difference between consecutive numbers increases by 2 each time. The differences are: 6-2=4, 12-6=6, 20-12=8, 30-20=10. Following this pattern, the next difference should be 12. Therefore, 30 + 12 = 42.
Question 3: Which word does not belong in the group? Apple, Mango, Banana, Carrot
- Carrot (Correct answer)
- Apple
- Mango
- Banana
Correct answer: Carrot
The words Apple, Mango, and Banana are all types of fruits. A carrot, however, is a root vegetable. Therefore, 'Carrot' is the word that does not belong in this group, as it is botanically distinct from the others.
Question 4: If all Roses are Flowers and some Flowers are Red, then what can be inferred?
- Some flowers are red (Correct answer)
- All roses are red
- No flowers are red
- All flowers are roses
Correct answer: Some flowers are red
The statement 'All Roses are Flowers' means that roses are a specific type of flower. The statement 'some Flowers are Red' indicates that a portion of the broader category of flowers possesses the characteristic of being red. We can only infer that some flowers are red, as the statement does not provide enough information to conclude that all roses are red or to make any other definitive statements about the entire group of flowers or roses.
Question 5: Which number should come next in the pattern: 3, 9, 27, 81, ?
- 243 (Correct answer)
- 162
- 324
- 225
Correct answer: 243
This is a geometric sequence where each number is multiplied by 3 to get the next number. The pattern is 3 * 3 = 9, 9 * 3 = 27, 27 * 3 = 81. Following this consistent multiplication, the next number in the sequence is 81 * 3 = 243.
Question 6: If John is older than Sam and Sam is older than Mike, who is the youngest?
- Mike (Correct answer)
- John
- Sam
- None of the above
Correct answer: Mike
The problem states that John is older than Sam, and Sam is older than Mike. This establishes a clear hierarchy of age: John > Sam > Mike. Based on this comparison, Mike is the youngest of the three individuals.
