NTSE Mental Ability & Reasoning

Question 1

If A is the father of B, but B is not the son of A, what is B to A?

Accepted Answer

Daughter

Answer

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, ?

Accepted Answer

42

Answer

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

Accepted Answer

Carrot

Answer

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?

Accepted Answer

Some flowers are red

Answer

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, ?

Accepted Answer

243

Answer

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.
