Question 28

Statements
O $ B, B @ S, S # E, E © R
Conclusions
I. S © O
II. R € S
III. B # R
IV. B # E

Solution

According to the given statements,
O>=B,B=S,S<E and E<=R
1st conclusion is true
O>=B and B=S
means O>=S which makes 1 tue
2nd conclusion is true
as R>=E and E>S which makes R>S
3rd conclusion and 4th conclusion is true
S<E and E<=R which means S<R.
Now B=S which implies B<E and B<R
