Read the following statement carefully and identify the conclusion that follows.Statement: No student of Class IX failed the science exam this year.
Conclusions:
I. The science exam was very easy.
II. All students of Class IX passed science.
A.Only Conclusion I follows
B.Only Conclusion II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Statement — conclusion
'No student failed' logically means every student passed — Conclusion II follows directly.
Nothing in the statement tells us WHY nobody failed; assuming the exam was easy goes beyond the statement — I does not follow.
Hence Only Conclusion II — option (b).
10
Identify the assumptions that must hold for the statement to be valid, then choose the correct option.Statement: The rapid development of artificial intelligence in healthcare promises to improve diagnosis accuracy, but concerns about data privacy still hinder its full adoption.
Assumptions:
I. Artificial intelligence has the potential to enhance diagnostic accuracy in healthcare.
II. Data privacy issues are a significant challenge in implementing AI in healthcare.
III. There are no concerns related to the use of patient data in healthcare AI.
A.Only I and II are implicit
B.Only II and III are implicit
C.Only I is implicit
D.All I, II, and III are implicit
Solution
Statement — assumptions
'Promises to improve diagnosis accuracy' assumes AI has that potential — I is implicit.
'Privacy concerns hinder adoption' assumes privacy is a significant challenge — II is implicit; III directly contradicts the statement.
Hence only I and II — option (a).

One number doesn't match this factorial series:
2, 6, 24, 122, 720, 5040
A.6
B.24
C.5040
D.122
Solution
Factorial series
The factorials are 2! = 2, 3! = 6, 4! = 24, 5! = 120, 6! = 720, 7! = 5040.
The 4th term should be 120, but 122 is given.
Hence 122 is the misfit — option (d).
18
Which number set is different?
(9, 18, 36), (10, 20, 40), (16, 32, 64), (17, 34, 102)
A.(9, 18, 36)
B.(10, 20, 40)
C.(17, 34, 102)
D.(16, 32, 64)
Solution
Number sets (x, 2x, 4x)
In the other sets the pattern is x, 2x, 4x — each term doubles.
In (17, 34, 102): 34 × 2 = 68, not 102 (102 = 34 × 3).
Hence (17, 34, 102) — option (c).
19
