**Quote:**

If each customer at the outdoor movie last night came in a car, what was the number of cars in which the customers came to the outdoor movie last night?

1) The average (arithmetic mean) number of customers per car coming to the outdoor movie last night was 2.

2) Total receipts at the outdoor movie last night were $4,500 at $5 per customer .

Well, I have a doubt regarding this problem.

If the average number of customer per car is 02, we can have range of possibilities: (lets assume that car have seating capacity of 04 people)

So, here in our situation the "Averaging/Balancing" concept will not work.

This question is from QPACK 01 and I think answer should be (E).

Official explanation incorrectly mentions (C).

Any expert replies please.

Thanks

Hi Vikasbansal227,

The Average Customer per car is Defined as follows

Average Customer per Car = (Total Customers) / (Total No. of Cars)

i.e. Total No. of Cars = (Total Customers) / (Average Customer per Car)Statement 1: Average Customer per Car=2i.e. Total Customers = (2) * (Total No. of Cars)

[Please note: The seating capacity has no role in this calculation, all that we need is the number of cars. Take example that a car with seating capacity of 1 may have only 1 customer and another car of seating capacity 5 can have 3 customers but together these cars have 2 passanger per car i.e. (1+3)/2= 2 passengers per car]But Since the

Total No. of Customers is unknown therefore

NOT SUFFICIENTStatement 2: Total receipts at the outdoor movie last night were $4,500 at $5 per customerTotal Customer = Total Receipts / Receipt per customer = 4500/ 5 = 900

But the The relation between Total Number of Customers and No. of Cars is unknown, Therefore

NOT SUFFICIENTCombining the two statements:From Statement 1: Total Customers = (2) * (Total No. of Cars)

From Statement 1: Total Customers = 900

i.e. (Total No. of Cars) = 900/2 = 450

SUFFICIENTAnswer: Option

Please Note: It's not a good Idea to doubt the Answers of Official Resource. Official resource is made after a lot of iterations and research and corrections.
