All X are Y
All Y are Z

I think ans is d.
Because from your point of you all the haromo are fluts.
There should be some instruments.

flutes=x
instruments=y
harmonium=z
all x=all y (1)
all y=all z (2)
so,all x=all z
all harmoniums are flutes
instruments=y
harmonium=z
all x=all y (1)
all y=all z (2)
so,all x=all z
all harmoniums are flutes

Excellent explanation @Prachi, you are right. Its very simple as if A=B, B=C.
Then C should always be equal to A, and applying same concept here there are flutes which are not harmoniums but all harmoniums are flutes for true.

A statement can convert into A2 statement to S2 statement. So can convert into all flutes are harmoniums.
Then both 1 and 2 follows.
Then both 1 and 2 follows.

Hi friends.
Can you explain the short cut in syllogism?

Let flutes be x, harmonium be y and instruments be z.
Therefore all y = z, all z = x.
Hence, all the harmoniums are flutes.
Therefore all y = z, all z = x.
Hence, all the harmoniums are flutes.

There are some conditions in syllogism.
For ALL = 100, 50.
SOME = 50, 50.
NO = 100, 100.
In conclusion the weight cannot be increased than statement, it can be decreased but cannot be increased, So conclusion 1 is wrong.
And one more to be remember if statement consist +ve, +ve then conclusion must be +ve.
If statement consist +ve, -ve then conclusion must be -ve. If statement consist -ve, -ve then No conclusion.
For ALL = 100, 50.
SOME = 50, 50.
NO = 100, 100.
In conclusion the weight cannot be increased than statement, it can be decreased but cannot be increased, So conclusion 1 is wrong.
And one more to be remember if statement consist +ve, +ve then conclusion must be +ve.
If statement consist +ve, -ve then conclusion must be -ve. If statement consist -ve, -ve then No conclusion.

@Prachi your second part is wrong I guess. As you have taken harmonium as z n flutes as x. Therefore z=x. Not all y= all z.
As per the second part. If my concept is wrong then please explain it to me.
