Explanation

The is the most tricky question on syllogism tht you may have sees. If you recall some different types of A proposition (see how to dters). mine the hidden proposition), you know that "A Bhimji are dishonest" is an A-type proposition because it makes a delf. nite exception. So, you may be tempted to infer that sin A+A=A hence ,All businessmen excpet Bhimjee are dishonewt +All dishonest people smoke =All busniness exceptBhimjee smoke... But this conclusion is erroneous. It may very definitely and corretly be inferred that .. All businessmen smoke excluding Bhimji whose smoking habits is that known. ..Statement I has two dimensions, One that .. All businessmen except Bhimji are dishonest, and two, which is hidden meaning that Bhimji is honest.. But it never told whether honest people stroice or not. However conclusion I, .. I businessmen except Bhimji smoke.. makes a definite assumption that Bhimji does not smoke This actually may or may not be true. Hence conclusiion I is wrong.
However, since conclusion U has a hidden propsition that .. Bhimji does not smoke.. and since conclusion II states that ..Bhimji smokes, one of the two conclusions mus be tre. Hence choice c.
The above example is a sample of the many tricks that the bage of syllogism contains. Theat are commonly called fallacies. Hoever, yest may overcome these by a little bit of practice and inteligence.
B= Businessmen except Bhimjee
BM= Bhimjee
D=Dishonest people
S= Smokers
