which means that I is also false, which makes sense.If IV is true, then III is false, which leads back to the impossible I being true.So C-say there are 100 people with 50% men & 50% women .......
If II is true, then that means I is also true, which can't be right as we know II is true here.
If III is true, the II is false, which means that I is also false, which makes sense.
If IV is true, then III is false, which leads back to the impossible I being true.
So C
say there are 100 people with 50% men & 50% women .
against bullfighting = 10
man = 3/10
woman = 7/10
Fraction of woman against = 7/43 [ amongst woman]
Fraction of man against = 3/47 [amongst man]
so that B
==============
obviously statement I is false [b'coz one of the following four statements is true.]
statement II is false [it states I is true]
statement III is true [as statement II is really false]
hence C
1) we're dealing with a percentage, which can be written as a fraction, so we could assume simply for the sake of finding the percentage that we have 100 people. 10% of that is 10. Now we have 7 out of 10 of these are women, so the other 3/10 are men. Now, we know that 3/100 of the people are men who are against bullfighting. Since there are an equal number of men and women, that lets us know we have 50 men. Therefore, as a proportion of all men, 3/50 are against bullfighting as (a) states
2) It is a law of logic that we cannot have a contradiction, or we cannot have p and not p.
Therefore, statements 1 and 2 are false because they lead to contradictions. Statement 3 says that 2 is false, which we just showed, thus statement 3 is true.
