Can somebody please help me in identifying the correct option with explanations.
In Patton City, days are categorized as having heavy rainfall (more than two inches),
moderate rainfall (more than one inch, but no more than two inches), light rainfall (at
least a trace, but no more than one inch), or no rainfall. In 1990, there were fewer days
with light rainfall than in 1910 and fewer with moderate rainfall, yet total rainfall for the
year was 20 percent higher in 1990 than in 1910.
If the statements above are true, then it is also possible that in Patton City
A. the number of days with heavy rainfall was lower in 1990 than in 1910
B. the number of days with some rainfall, but no more than two inches, was the same
in 1990 as in 1910
C. the number of days with some rainfall, but no more than two inches, was higher in
1990 than in 1910
D. the total number of inches of rain that fell on days with moderate rainfall in 1990
was more than twice what it had been in 1910
E. the average amount of rainfall per month was lower in 1990 than in 1910

D. the days for light rainfall and moderate rainfall is less in 1990 compared to 1910. In other words, days with no more than 2 inches rainfall in 1990 is < in 1910. There fore the C & D are out of Q bcoz it's given in the Q that the Light and Moderate rainfall IS LESS in 1990.
If the L & M Days are less in 1990 than in 1910 then only 2 things can make a difference,
1. either the Heavy rainfall days were high
ii. or in same no of days of L & M Rainfall, the amount of rain was more than the amount in 1910.
We do not have an option for #1 (A proves otherwise) and for #2, the D gives an evidence as in 1910, the rainfall could have been 1 inch and in 1990, it could be 2 inchec, thus increasign the % of rainfall.

Oh man, this is a hard one...
Is it A?
Here's my reasoning, let me know if it's shotty.
A: No way, there must be more days because the "Light" and "Moderate" are both lower.
B: Can't be the same, they said 1990 was less.
C: Can't be higher, they said 1990 was less.
D: Total number of inches on days with moderate in 1990 was twice than 1910, can't be.
E: This can't happen if 1990 was twenty percent higher.
Holy crap, I ruled them all out.
I went over the ones I liked:
A: Umm...well, this may be true, because if it's heavy rain, then it can go over 2 inches...it could have rained 100 inches in one day and still had less number of days of heavy rain in 1990 than 1910.
D: Total number that fell on days with moderate...still can't happen.
I picked A. If this isn't right, I need someone to put an in depth answer, cuz it looks like all of the answer choices suck.

Considering your point 1.nikita27 wrote:D. the days for light rainfall and moderate rainfall is less in 1990 compared to 1910.

Can't we have fewer days (fewer in 1990 than in 1910), and still end with more rainfall than in 1910. In that case Option A stands a chance. This logic is similar to what you did for point 2.
Am i missing some thing ?
Rohit, Please let us know the source of the question.

Damn, after reading what Nikita and Pandey wrote, I'm back to choosing A or D....
But I still want to rule out D because there's no way it can happen. The most moderate rainfall that can happen is 1.99 inches of rain in 1990 and the least is 1.00 in 1910. 1990 rain cannot go above 2.0 inches. If the rule is that there were less days of rain in 1990 than 1910, but the answer choice states that the total rain fall in 1990 is twice than 1910, then D is only possible if there were more days of rain in 1990 than 1910.
