They are saying "the first n car shows"
Now this could be interpreted in two ways.

1) The first n "annual" car shows. This is what you are saying I believe, then it makes perfect sense.
2) But they could also be talking about individual car shows. For example in the first annual car show (2004), there were 38 car shows and n of them (where n < 10) had the specified pre-registration and on-site registration fees. This is how I interpreted it. In the sense there every car has an individual "show". But I get your point that all cars combined is what they mean by "car show" over here.

Regardless, not super pepped about the wording here. They should have used the word annual.

You’re wrong. We are in fact given clear data about the registration fees: for the first n years, they were $10 and $12, and for the remaining years, both fees were higher. Since 2005’s numbers fit perfectly with $10 and $12, that means 2005 was one of those early n years.

But 2006’s data doesn’t fit those same fees. With 28 preregistered and 67 on-site, 10 and 12 would give only $1084 (28*10 + 67*12 = $1084), not $1341. So 2006 must have been the first year when the registration fees rose.

You can even see this without doing the math: the total number of cars changed slightly, from 92 to 95, yet the total revenue jumped from 1040 to 1341. Three extra cars could not have produced $301 more in revenue under the same fees. Hence, both preregistration and on-site fees must have been higher in 2006.

I'm still confused on the 3rd one. Is it a data sufficiency question? For eg, if the revenue per car wasn't the highest in 2010- would the answer still be Yes because it can be determined with the given data?

No, it is not exactly a DS question but I qould say opposite of it.

In DS, you check whether the information in statement(option) is sufficient to answer the question in main para.

Here, you have to check whether the information/data/details in main para are sufficient to confirm the option.

For each statement, select Yes if it can be determined from the information provided that the statement is true. Otherwise, select No.

Now the statement in the option is already given to be true. You have to find whether the information in the para is sufficient..

Hi veroaperiam,

Great question, and you've actually put your finger on a spot where the thread's "it's just data sufficiency" shorthand can mislead you.

Here's the precise answer to what you asked: no - if the average revenue per car were not highest in 2010, the answer would be "No," not "Yes."

Why "sufficient" alone isn't enough

Look at the exact wording of the stem: "select Yes if it can be determined that the statement is true." To earn a Yes, two things both have to hold:

- The data must let you settle the matter (sufficiency), and
- What it settles must be that the statement is true.

So if you crunched the averages and found the peak was, say, 2009 instead of 2010, the data would still be "sufficient" - but it would prove the statement false, and you'd select No. Sufficiency by itself never forces a Yes.

Where Karishma's "you don't need to solve it" comment comes from is just a time-saver: every year gives you Total revenue / Total cars, so you can find each average and confirm 2010 is the max. You don't have to grind all 14 - but conceptually the statement does have to come out true. It does here, which is why Yes is correct.

A quick parallel to lock it in

Imagine statement 3 instead read: "The year with the greatest average revenue per car was 2009." The data is exactly as available as before - fully sufficient to compute every year's average. But when you compute, 2010 wins, not 2009. The claim is determinably false, so the answer flips to No.

Same data, same "sufficiency," opposite answer. That shows the verdict rides on whether the statement turns out true, not merely on whether you can compute it.

So your instinct was right to question the pure-sufficiency framing - the statement genuinely has to be true for a Yes.

Answer: Yes
