Answers :-



1. 1; No bat is a book + Some books are balls = E + I = O*
= Some balls are not bat Hence, I follows. But we
can’t proceed further. Hence II does not follow.

2.5; The  possibility  in  I  exists  as  there  is  no  negative
statement. Again, All squares are circles + All circles
are ice = A +A = A = All squares are ice  conversion
Some ice are squares. Hence, II follows.

3.4;   I + I = No conclusion

4.1; Some bananas are soups + No soups is a powder = I
+ E =  O  = Some bananas  are  not powder. Hence,
conclusion I follows. Again, No curry is a banana +
Some bananas are soups = E + I = O*= Some soups
are not curry. Hence, conclusion II do not follow.

5.5; All balls are tables + All tables are chairs = A + A = A
= All balls are chairs. Now, All balls are chairs + No
chair is a room = A + E = E = No balls is a room Hence
conclusion I follows. Again, All tables are chairs + No
chair is a room = A + E = E = No table is a room. Hence,
conclusion II follows.
