Question

Statements:
Some pearl is jam.
All jam is block
No block is iron.
All iron is sword.
Conclusions:
1. Some pearl is block.
II. No jam is iron.
III. No block is sword.
(A) Only I and II follows
(C) Only II and III follows
(B) Only I and III follows
(D) All I, II and III follows​

Answer 1

option (D) i.e., All I, II and III follows

Answer 2

Only I and II follows.

* This is a case of syllogism which can be solved using a venn diagram( attached below).

* Jam is a sub circle within a bigger circle, block so any condition for block will be followed by jam as well.

So, no block is iron also denotes that no jam is iron( Conclusion II is true).

* Since pearl shares a common part with jam, it will also be sharing a common part with block ( so conclusion I is true).
