there are many errors in conclusion

=> they didnt use both statments while concluding
=> common word must be divided atleast one in statements
=> word which is not divided in the statement can't be divided in the conclusion. here, statement II disobeys this rule

16x15x14!/17 => 16/2

ek statement se conclussion ni ho sakta kya .. ?

eg: in this question conclustion 2, is nothing but a form of statement 1


@Brooklyn bhai option D hoga:

Statements : Some nurses are nuns. Maya is a nun.
Conclusions : I. Some nuns are nurses II. Some nurses are not nuns.

1st statement main nurses are distributive and not nuns hence conclusion 1 is gone.
when premise is positive then how conclusion can be negative hence conclusion 2 gone?
what say?

bhai dekh ye to c'mon rule to universal hain ki conclusion mein dono statements ko use karke conclusion aana chahiye !

ab agar tu conclusion dekhaga tu usme dekh it is using only statement I ...statement II ko chua bhi nahi

this is a major flaw
