This is a fairly simple DS problem, however, I got tricked when I had to choose between C or E.
First, I thought this question was similar to this:
https://gmatclub.com/forum/will-the-fir ... fl=similar
When combining C and E, I picked E because statement 1 said the average person per car was 2. The word "average" threw me off because it was an average and not a solid number of people. However, the OA is C.
1&2)
4500/5 = 900 customers
900/2 = 450 cars
Can anyone provide any similar DS questions whose tricks use averages in this way?

Hi,
1) Tells us only about average no of person per car=2. It does not elicit anything about the total no of people or total no of cars in which they might have come.
2) $4500 @ $5 per person menas in total there were 900 person. Again, we cant say how many cars.
While if we combine both, we know average = sum total of all quantities / no of quantities
=> no of quantities = sum total of all quantities/average = 900/2 = 450.
Coming to your doubt obetween C and E, remember average reveals how many each can have if distributed equally. Hence the quantities which are moe than average will be balanaced bu those that have less than average. So in this case, some cars may have more than 2 person but then this extra will be offset by those that have less than 2 person per car. I hope this helps.

statement 1- avg 2 persons per car. fine. but how many cars? 4,5 or 20? not suff.
statement 2- no of people - 4500/5= 900. but came in how many cars? 900 @ 1/car or 450 @ 2/car?
both statements together- since avg 2 person per car, 900 can come in 900/2 = 450 cars only.
hence ans = C
