All A are B ---> some B are A.

According to that the 1st conclusion is subjected to one more derivative.

How is the second statement true? Can someone please explain it in an easy way?

Rishi said:   10 years ago
The right answer is A.

All+All=All.

All the pencils are inks.
Some inks are pencils.

Why don't we take as either case? I mean either 1 or 2.

Hello I don't understood how the second statement are true because we can't draw the solution because it may or may not be says that some inks are pencil. So please explain it, how it is true?

I guess this type can be solved fast only with circles. Otherwise I spent lot of time making conversion, looking to the M-distribution, figures and types (AII-3, etc. ) , making second sentence first, etc.

How the second statement comes true please explain it?

Bhaskar said:   1 decade ago
Just convert the first statement.

By rule of conversion.

All -> some.

No -> somenot/no.

Some -> some.

There may be a chance to inks to be pencils.

Both sentence are universal affirmation hence conclusion must be universal affirmation and it should not include common term (pens). Hence conclusion first is right it again.

If all the pencils are inks then we can also conclude that some inks are pencil because sentence is not saying that all inks is pencil. Hence second also follow.
