1)Only Yousef is compatible with Aisha since Yousef quotes about the importance of all the three medals in ranking and also gives a strategy to decide about the points by giving an equivalent value to silver and bronze medals,while the other two (Ahmad & Farida) didn't talk about the importance of individual medals.


2)a)No,since we have the ranking based on total medals per capita and not on total medals and that too we just know the total points for 2004 and there are many possibilities between total number of medals and total number of points.

b)Yes,since we know the criteria given by Yousef so we can get the total points and then use Yousef's formula to get the exact count of individual medals and then decide the ranking in 2008.

c)Yes,since we know the criteria given by Yousef so we can get the total points and then use Yousef's formula to get the exact count of individual medals and then decide the ranking in 2012.


3)a)Yes,since per the table ,according to total number of medals country C is 1st,thus satisfying Ahmad's criteria.
b)No,since if we go by Farida's logic to include country's populationand we see total medals per capita,total gold medals per capita and weighted medals per capita than the ranking is different in all the criteria.
c)No,since Taka's logic says to count on gold medals and according to that G&H are achievers.
d & e) We cannot comment here because although Yousef talks about weighted medals concept but he doesn't talks about per capita sin e he doesn't want to include population so we cannot define an achiever here.

can you please explain question 2?
Total weighted medals in 2008, calculated as per Yousef’s recommendation.

I'm not able to understand how to calculate weighted model from total points given in graph.

Thank you for your help.

What Yousef wants:-
Total weighted medals is to consider a silver broze as 1/2 gold and bronze as 1/4 gold. Thus ratio of G:S:B = 1:(1/2):(1/4) = 4:2:1

­And this is what is given in graph too, just that graph talks of point and not medals.

To convert points to number of gold medals, divide points by 4, as 4 points = gold medal.

In Tab 1, Yousef says: Yousef recommends counting each silver medal as half a gold medal, and each bronze medal as half a silver medal. So he recommends giving different weights to different medals in the total score. 

Look at Tab 3 - Graph
'Weighed medals' means gold, silver and bronze have different weightage in the total score. Gold medal has 4 points, silver has 2 and bronze has 1. So a silver medal has half the points of gold and a bronze medal has half the points of silver (as Yousef recommended). Hence in 2008, country C had maximum score under weighted medal measure.

Question 2. 

­2. For each of the following measures of Olympic achievement by countries, select Yes if the information given clearly indicates that 1 of the 6 countries discussed received a higher ranking than the other 5 by that measure in the year indicated, and which country this is. Otherwise, select No.

Look at Tab 3. It has the table giving points tally of top 3 performers in each year. How are points calculated? 1 Gold medal = 4 points. 1 Silver = 2 points, 1 Bronze = 1 Point

Total number of medals received in 2004.

In 2004, C had 62 points and H had 47 say.
Does it mean C had more medals than H? No. 
C could have 15 gold and a silver medal while H could have 47 bronze medals. 
So we cannot find who had maximum total number of medals.

ANSWER: NO 


Total weighted medals in 2008, calculated as per Yousef’s recommendation.

Yousef recommends counting each silver medal as half a gold medal, and each bronze medal as half a silver medal.
A gold medal is not equal to a silver medal. Hence to establish equivalency, we can say that 1 silver medal = 0.5 gold medal and 1 bronze = 0.25 gold. 
Imagine replacing every silver medal with half of a gold medal and every bronze medal with a quarter of a gold medal so that everything can be calculated in terms of gold medals. So we have made them comparable and hence can add them. 

The points table does exactly this. It gives 4 points to Gold medals, 2 to Silver (counting it as half a Gold medal) and 1 to Bronze (counting it as half a Silver medal)
In 2008, C had 42 points and H had 25 points. So C had maximum of the weighted medals. 
Say C had 10 Gold and 1 Silver medal (as per points)
and Say H had 25 Bronze medals (as per points)

This means C has 10 + 0.5 weighted medals = 10.5 gold medals
and H has 25 * 0.25 = 6.25 gold medals

Since C has maximum points, it means it has maximum weighted medals. 

ANSWER: YES


Total weighted medals in 2012, calculated as per Yousef’s recommendation.

Exactly same as above for 2012.

ANSWER: YES­

Shouldn't Q3's option D also be valid - according to the graph for 2008 which aligns with Yousef's strategy, Country C has the heighest points.­

Same question: According the graph, C in 2008 has the highest weight. Can anyone help explain?

Hi. I agree that D would also be valid. The second table shows that country C got the most points based on Yousef's system. However, the official explanation disagrees and states the following (which I do not agree with). I feel this is a questionable question unfortunately 😭

OFFICIAL EXPLANATION:
Yousef wants to weight countries’ medals, counting each silver medal as half a gold, and each bronze medal as half a silver. But it is unclear from the discussion whether Yousef would calculate these weightings per capita, which the table clearly indicates would put Country C second to County E in the rankings (excluding D)

I have added a note to the question to hopefully save some frustration for other test-takers. I agree with everyone here that #3 appears to have 2 correct answers, at least until someone much smarter can prove otherwise, which is always encouraged!

I am not sure there is much learning here besides the fact that sometimes bad questions come up and on the GMAT they are likely experimental, so exactly! don't overthink it and move on to the next question. Don't burn all of your time on a single question. If it is experimental, it won't even count.

How is Q3 A - correct option? How are we counting the total no. of medals which according to Ahmed is an achievement?
In both graph and table, we get the points and rankings basis the weighted totals. How do we know what is the total medals?

Look at the discussion above - there are issues with question 3. There is the official explanation as well, you can read through that too - all in this discussion :angel:
