Statements:
Some rice is white.
Some rice is brown.
No white is wheat.
Conclusions:
I) Some wheat is brown.
II) Some rice is not wheat.
III) Some brown is not white.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only II.
The least possible Venn diagram is:
I) Some wheat is brown → Does not follow (As there is no direct relation between wheat and brown so it does not follow)
II) Some rice is not wheat → Follows (As, some rice is white and no white is wheat so, definitely some rice is not wheat.)
III) Some brown is not white → Does not follow (It is possible but not definite)
Thus, Only II conclusion follows.
