Discussion Forum : Syllogism - Syllogism 1 (Q.No. 2)
Directions to Solve
In each of the following questions two statements are given and these statements are followed by two conclusions numbered (1) and (2). You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusions and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.
Give answer:
- (A) If only (1) conclusion follows
- (B) If only (2) conclusion follows
- (C) If either (1) or (2) follows
- (D) If neither (1) nor (2) follows and
- (E) If both (1) and (2) follow.

@Hanuman.
Statements (both premises and conclusions) are represented as follows: Statement Notation
a) All S are P, SS-P
b) Some S are P, S-P
c) Some S are not P, S / PP
d) No S is P, SS / PP
RULES:
1) Conclusions are reached by connecting Notations. Two notations can be linked only through common linking terms. When the common linking term multiplies (becomes double from single), divides (becomes single from double) or remains double then the conclusion is arrived between terminal terms.
2) If both statements linked are having " signs, resulting conclusion carries " sign
3) Whenever statements having " and / signs are linked, resulting conclusion carries / sign.
4) Statement having / sign cannot be linked with another statement having / sign to derive any conclusion.
For this question:
By Raval notations HH -I II -F so HH - F follows.

Can you explain Raval Notations with example?

It's simple.
It says all the instruments (A) are flutes (B). But all the flutes (B) may not be instruments (A).
Basically flutes (B) includes all instruments (A) but instruments (A) does not includes all flutes (B).

Very easy Simple trick for inner and outer circle problem.
If we move from inner to outer circle two conclusions are correct (all+some), whereas if we move from outer to inner only (some) conclusion is correct.
All flutes are instruments (we are moving from outer to inner so only "some" conclusion correct), all harmonious are flute (we are moving from inner to outer hence in conclusion wherever "all and some come that is correct).

I think it is E.

I think the answer is E.
The diagram in explanation shows only one situation that harmoniums are making a portion of instruments. But as per set theory, the complete set is also a subset of the given set. It can also be true that if all harmoniums are instruments, all instruments are also harmonium. Similarly in the second sentence.
In such case, option E is the answer.
