To keep things simple, Population for both = 100
I'll explain the most Restrictive scenario

S County
Population 100
# Of Household greater than or equal to 60K = 10
# Of Household Between 40K to 60K = 0

% above 40K = 10% AND % above 60K = 10%
None between 40 to 60 range but still satisfies conditions

M County
Population 100
# Of Household greater than or equal to 60K = 9
# Of Household Between 40K to 60K = 2

% above 40K = 11% BUT % above 60K = 9%
Some has to be in that 40 to 60 range, otherwise wont satisfy condition

Hence C is the Ans

The whole goal is the confusion of %age vs numbers.. You can't assume both counties have the same total no of households. If that were the case, the answer would be an obvious D.

Here is a scenario:

Answer is C.

There have to be some households that have incomes between 40K and 60K

B is the correct answer! I met it in the OG 13th and Im sure that the correct one is B, NOT C

everyone is saying the answer is B but when i marked B as my answer the system gave C as the right one.
Can anyone check on this

Check the correct answer by the statement and not just by the correct answer tagging A/B/C/D/E.

Correct answer is : Some households in Merton County have an annual income between $40,000 and $60,000. (Regardless of whatever tagging has been made to the answer choice - A/B/C/D/E.

this is a common pattern in gmat, test takers should know this, also, this pattern is relating to percentage and numbers, but the right answer turns out to connect with sth else.

Scenario:

Merton has 1 person who earns $1 per year and 6 people who earn $61,000 per year.
% = 85.8

Sommer has 1 person who earns $1 per year and 10 people who earn $61,000 per year.
% = 90.9

Now how is option C valid?

Hi dejavu619,

You missed a key portion of the argument. The question stem states that Merton county has the highest percentage of households with an income greater than $40,000. If you account for this in your equation above, you will see C to be the answer.

To do the math: Merton has the highest % of households with 40,000 + income; Sommer has greatest % of 60,000 + income. Given this, we can safely show that SOME (even 1) have an income greater than 40,000, but less than 60,000 in Merton.

Does this help?

The scenario I have posted doesn't prevent Merton from having the highest % of households with 40,000+ income. There doesn't need to be anyone between 40k - 60k for Merton to have the highest % of households with 40,000+ income.

dejavu619,

The percentage of households with an annual income of more than $40,000 is higher in Merton County than in any other county. However, the percentage of households with an annual income of $60,000 or more is higher in Sommer County.

Where do you address the first line? According to your math, only Sommer county has a higher average of $60,000 + residents. How do you account for the greater percentage of $40,000 residents in Merton? Your math only accounts for one of the premises, but not both together.

Does this help?

A country can have highest % of people earning more than $40,000 without having any citizens between 40k-60k. For instance, $66,000 comes under the "higher than $40,000" category (as well as higher than $60,000 category), doesn't it?

It does, but your scenario only accounts for ONE of the premises. Both premises, under your scenario, cannot be true. You need someone in the 40-60k range to make your scenario fit the bill.

Your scenario:

Merton has 1 person who earns $1 per year and 6 people who earn $61,000 per year.
% = 85.8

Sommer has 1 person who earns $1 per year and 10 people who earn $61,000 per year.
% = 90.9

In your example, Sommer has a great percentage of people who make more than $40,000. The premise states that Merton has the highest percentage. Do you see the difference? You only account for the second premise.

Does this help clarify any further?

Yes, I realized my folly. Thanks a lot for your patience and explanation :)
