Answer 1

See here given facts are

s1.some big are small.

s2.no small is large

s3.some large are tiny

So you can make pictorial pictorial representation.I am here just contradicting the conclusion.

1. some large are not big

Here only information given is no small is large.We can;t conclude that some large are not big there is possibility that some  large are big. So given conclusion is false.

2.no big is large

If some some  large are big then given conclusion is directly false.

3.some small are not tiny

We don,t conclude which small are not tiny .We only give the fact that some small are tiny .So given conclusion is false.

 4. some bigs are not tiny

Same as above .So given conclusion is also false.

So none of the conclusion are following .

Answer 2

I think C is the answer.....correct me if i am wrong

1. some large are not big

--> wrong,  diagram case 2 explains large can be part of big, from given data we can not conclude that

2. no big is large

--> wrong diagram case 2 explains large can be part of big, from given data we can not conclude that

3. some small are not tiny

--> i have not shown this in diagram,  but small which are not large could be tiny( its possible )

4. some bigs are not tiny

-->  no, from given data we can not conclude that

@ManojK Is above diagram correct.?

Answer 3

draw venn diagrams such that maximum possibilities are eliminated ans is e) none follows

draw 4 circles each for small big and large , tiny only small and large circle will not intersect at any point rest will have something in common
