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.

@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.

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.

See inner (means down to up) to outer all + some both are follows. But outer (means up to down) only follows some.
