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
The main point-
(number of rainy days in 1910 > number of rainy days in 1900)
doesn't mean
(rainfall in 1910 > rainfall in 1900)
pretty obvious as the amount of rain in a rainy day coupled with number of rainy days will determine that.

A. the number of days with heavy rainfall was lower in 1990 than in 1910
There is possibility.

B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910
False. it is greater in 1910 than in 1900.
C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910
False. it is greater in 1910 than in 1900.
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
1 inch < moderate (1910) < 2 inches
1 inch < moderate (1900) < 2 inches
moderate (1900) > 2 *moderate (1910)
Impossible. simple arithmetic.



E. the average amount of rainfall per month was lower in 1990 than in 1910

the rainfall in 1900 is 20% higher than in 1910.
So the average amount in 1900 has to be higher than in 1910.
Wrong.


A is the most suitable one. Correct.

This question seems to be a bit confusing. It will really be helpful if someone can explain properly. :)



Here is very good explanation https://www.veritasprep.com/blog/2013/0 ... -the-gmat/

B , C and E can be eliminated easily as they contradict the facts in stem. Choice D can't be true , If we pay attention to the stem. Moderate rainfall is > 1 and <= 2 . So 2 times of 1.00001 will be 2.00002 , which is more than 2 inch. Hence , by the information in stem this choice can't be true and is incorrect.

Option A can be true assuming certain conditions.

Yes, a higher number of days with heavy rainfall in 1990 is certainly possible and would, in fact, be the simplest solution. But it's not the only possibility.

The key to this question is to realize that each category represents a range of rainfall amounts. For example, we know that in 1990 there were fewer days with moderate rainfall than in 1910. But moderate means 1-2 inches. Even though the number of moderate days was higher in 1910, we don't know whether the total rainfall during those moderate days were closer to 1 inch or closer to 2 inches.

Perhaps most of the moderate days in 1990 were closer to 2 inches and most of the moderate days in 1910 were closer to 1 inch. In that case, it would certainly be possible for the total rainfall on moderate days in 1990 to be HIGHER than the total rainfall on moderate days in 1910, even though the number of moderate days was higher in 1910.

Similarly, the number of heavy days in 1910 could have been higher, but the total rainfall during those "heavy" days may have been barely higher than 2 inches on average. On the other hand, 1990 might have seen fewer heavy days, but the total rainfall during each of those heavy days could have been massive. Thus, the total rainfall in 1990 could have easily been higher even if the number of days within each category was lower.

So while it is certainly possible that there were more heavy days in 1990, this does not HAVE to be true.

I hope that helps!

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


The question is asking for an option that is possible but not necessarily true.
Stimulus tells us:
HR > 2
MR 1 to 2
LR 0 to 1
No Rain 0

LR Days (1990) < LR Days (1910)
MR Days (1990) < MR Days (1910)
Yet, Total rainfall 1990 > Total rainfall 1910

A. the number of days with heavy rainfall was lower in 1990 than in 1910
This is possible. Even if HR Days (1990) < HR Days (1910), still 1990 could have had higher total rainfall. Think if in 1990, HR days were fewer, but on each one of those days, it rained 50 inches whereas in 1910, HR Days were more but on each one of those days, it rained only 3 inches, then total rainfall in 1990 could be higher than that of 1910. This is the answer.

B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910.
Not possible because it is given that
LR Days (1990) < LR Days (1910)
MR Days (1990) < MR Days (1910)
So LR Days (1990) + MR Days (1990) < LR Days (1910) + MR Days (1910)

C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910
Not possible because of the reason given in (B).

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
Not Possible. On a moderate rainfall day, amount of rainfall is more than 1 but less than 2. If number of MR days in 1990 is less than the number of MR days in 1910, no amount of rain can make the total rainfall more than twice.

E. the average amount of rainfall per month was lower in 1990 than in 1910
Not Possible.
Total rain (1990) > Total rain (1910)
Average rain per month = (Total rain)/12
Total rain (1990)/12 > Total rain (1910)/12



it is given that the days of LR and MR, but didn't give the day of no rain.
and there's an situation:the rainfall of heavy rain is very large, and NO rain days in 90 are more than in 10, so B and C are possible?
