Three statements are given followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
Some telescopes are periscopes.
Some telescopes are microscopes.
Some telescopes are kaleidoscopes.
Conclusions:
I. Some kaleidoscopes are telescopes.
II. Some microscopes are kaleidoscopes.
III. Some microscopes are telescopes.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only conclusions I and III follow
The least possible Venn diagram is
I. Some kaleidoscopes are telescopes. True (It is given that some telescopes are kaleidoscope so the reverse is definitely true)
II. Some microscopes are kaleidoscope. False (no there is no definite relation given between them)
III. Some microscopes are telescopes. True (It is given that some microscopes are telescopes so it is definitely true)
Hence, the correct answer is Only conclusions I and III follow.
