Sorry to open a new thread .. but dont know why I am getting this wrong:
m05-q12-73440.html

4% of population of country L has military experience and supports a war against Country G. If 20% of those who support the war have no military experience what percentage of the country's population actually supports war against G?

(A) 5%
(B) 7.5%
(C) 10%
(D) 12.5%
(E) 15%

I did it this way:
Total Population = 1000
Support war -- 40 --> Don't support war -- 960
So 40 + 2% of 960 should give us the answer i.e. 23.2% ..
Am i wrong somewhere?

You need to calculate percentage of people who support war. Why are you adding 2% of the people not supporting war to 40 ?

Since 20% of the population who supports war doesn't have military experience , 80% of the people supporting war does have military experience.

So 40 = 80% of the people supporting war
Total no of people supporting war will be (40/0.8) 50 and hence 5%

Answer should be A

Here 40 are not the only ones supporting war, instead these are people who have military experience also in addition to support war. Now what is given is "20% of those who support the war have no military experience" hence there are "80% of those who support the war have military experience" so,
.8x = 40 where x is people who supports war
x = 50 which is 5% hence A.
