The two charts show how female and male survey respondents answered

Please post the official answer?

Although I got this wrong, does "at most" includes "rarely and infrequently" both ? If that is the case, then 20% females and infrequently should be the answer.
I did not notice the at most part and marked 30% male and rarely instead.

Yes, at most would include everything that is below it.
For example: If data gives you number of students and scores in groups of 10, viz 10-20, 20-30 and so on, at most 80 would include all groups under it till 70-80.

I got the answer as slightly 'less than 40% female, occasionally', which does not really seem wrong either. Am I missing out on something?

 
­Hi chetan2u, options in the 1st blank seem wrong. Would you look into it? According to this video (https://www.youtube.com/watch?v=hM4nVta ... Fb&index=2) from 21:00, option 3 should be 30% of female.­

anish777 I think you marked correctly when choosing '30% male and rarely', take a look at the explanation of gmat ninja in the video I included above­­

Thank you jaky_nguyen

Answer: ­

That’s not “slightly” less than 40. It’s soo many distance to 40

Posted from my mobile device

The 0.2, 0.4 etc figures on the pie chart show the fraction of respondents corresponding to 20%, 40% etc.

So a bit less than 0.2 of the female respondents (say about 19%) said that they ate that food rarely (about 8%) or infrequently (about 11%) - approximately.
A bit less than 0.4 of the female respondents (say about 38%) said that they ate that food rarely (about 8%) or infrequently (about 11%) or occasionally (about 19%) - approximately.
and so on. 

This is how you will read the graphs. 

Slightly less than ____ respondents indicated that they ate the food at most ____.

When we say 'at most' we are including all the regions before it. So if I say "30% respondents said that they ate that food at most occasionally" it means that "30% respondents said that they ate that food rarely or infrequently or occasionally".

10% of male is the middle of rarely so more than 10% of males ate that food rarely. Hence this will not fit in the options. 
A little less than 20% of females (about 19%) did say that they ate that food at most infrequently (i.e. rarely + infrequently). Hence this works. 

ANSWER: 20% females, infrequently

Note that none of the other options work. 30% females is right in the "occasionally" section and 40% males are well into the "infrequently" section.

I got the answer as slightly 'less than 20% female, occasionally', wHAT IS WRONG IN IT

­Hi krispy289, you picked 'less than 20% female', correct? Now see the below table which I created just eyeing the pie charts. Do you see that for slightly less than 20% of females, the column header is 'Infrequently'? If it were 'occasionally' in the women's category, the percentage would have fallen between 19 to 38 approx.

Hope this helps.

Hi experts, I hope you are doing fine. My question is regarding, why can't the correct answer be, B). 20% female and C). Ocassionaly. It seems that a very small amount of the occasional section(female) should also be considered in the slightly less than 20% if you look at the pie chart. Thanks for taking the time to answer my question.
Final answer:Slightly less than 20% of the female respondents indicated that they ate food at most occasionaly.

The wordings made this a little complex and difficult to comprehend. But, here is what my thought process was let's say the answer to the question about how often they ate a certain type of food was 0.2 this is actually, 20% chance of eating. So, it starts from 0 till 20.

Now, the Slightly less than part in question is where I searched for a line closer to the indicator/marker lines (0.2,0.4,0.6,0.8,1.0).This is where I saw the line slightly less than 0.2 of female pie chart. And the drop down box confirmed it. Selected.

Next - Infrequently actually includes foods infrequent and rare(coz it started from0). So, infrequent was the one which was at most from 0 to 0.2

Having said this, it still all remained a little ambiguous and took 3.5 mins.

Please correct me if my reasoning has flaws.

Hey Karishma,
Thank you for your explanation. It definitely makes sense and is the right answer.

But can you shed some light on why "at most" means that we always start at 0, summing up the categories? In my first attempt, I assumed that each slice of the piece essentially sums up to 100% or 1. Why do we need to include rarely when answering for infrequently, and why do we include the former 2 when answering for occasionally?

Cheers.

Official Answer:

The table below gives rough estimates from the charts that are sufficient for solving this problem. For example, in the chart for female respondents, the angular diameter of the sector for “rarely” is clearly less than the angular diameter of the sector for “infrequently”, and both sectors combined make up about 20% of all female respondents. Therefore, less than 10% of the female respondents responded with “rarely”, or equivalently, “at most rarely”.

	Female	Male
at most rarely	less than 10%	about 30%
at most infrequently	slightly less than 20%	more than 40%
at most occasionally	more than 35%	more than 50%

RO1
Selections A and D can clearly be discarded by looking at the estimates in the male column of the table above, and selection C can clearly be discarded by looking at the estimates in the female column of the table above.
The correct answer is 20% of the female.


RO2
In the table above, only selection B (infrequently) is paired with “slightly less than 20%”.
The correct answer is infrequently.
