Explanation : According to squares of opposition: The logical
form of ‘None of the flowers is fragrant’ is ‘No flower
is fragrant’ (i.e., E type). It can be converted only to
I type, that is statement IV (the logical form of ‘Most
flowers are fragrant’ is ‘Some flowers are fragrant’).
In each of the questions below, two statements are given followed by an inference.
Explanation : There are three terms. Both are I type, even after
conversion for alignment purpose, they will be of I type
as shown below.
‘Some intelligent people are happy’, we get
Some who are happy are intelligent (I type)—first
Some intelligent people are rich (I type)—second
I + I = No inference. So, option (d) is the answer.
