total rainfall for the year was 20 percent higher in 1990 than in 1910.

rainfall was higher, not the no of days of heavy rainfall in 1990 was greater than the no of days in 1910 (this is what i was looking for in the option)

i will try to explain it with an example

this means that it rained 2 days with a heavy rainfall of 10 inches in 1990 and it rained 5 days with a heavy rainfall of 2 inches in 1910
total 20 inches total 10 inches

hope it helps!

I choose D because:-

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 (atleast 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.

Say in 1990 the no.of days with light rainfall was 10
In 1910 it were 20.

Say in 1990 no.of days of moderate rainfall was 15.
and in 1910 it was 20

Total rainfall in 1910=100cm
Total rainfall in 1990=120cm

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.

No.of days of heavy rainfall can or cannot be greater in 1910.
because in one day in 1990 a heavy rainfall can give 20cm or 2.1 cm of rain.

B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910.
This is also not necessary

C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910.
It is given that it was fewer in 1990

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.
After applying POE i am left with this option.
This some what makes sense to me.That even if der was no heavy rainfall then too rainfall would have been greater in 1990

E. the average amount of rainfall per month was lower in 1990 than in 1910.
we cannot determine this.But i think that it is given that it was higher in 1990.

Please explain where i am wrong.........

I took 10+ minutes to solve the question, and marked the wrong option. While revisiting the question, I realized that I overlooked the days defined as "no rainfall" . How to improve on concentration or focus in a short time - could anyone help me...

Though, I am not sure about your case, but it seems that you have also missed to take the "number of days with no rainfall" into consideration. I kept on thinking on the similar lines for more than 10+ minutes, and it is only after re-visiting the question, I realized where I was wrong.

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.

Please explain where i am wrong.........

You're assuming a fixed value for the amount of rain on high, moderate and low days. However, the stimulus says that the days just have to fall within a range and the example you provided is reasonable but you've exaggerated the margin of days and used a fixed value which forces D to be correct. What if there 10 moderate days in 1990 and 11 moderate days in 1910? And what if the amount of rain of the moderate days in 1990 was 2.5 on average while the moderate days in 1910 averaged 2 inches? See what I'm saying?

B,C,D,E are all certainly wrong.

D is wrong b/c of definition, the amount of rain in moderate days in 1990 cannot be twice as much as that in 1910.
