Looking Best Guess:How many products has been sold at least once, by this supermarket in its first 2 weeks?

Question

Additional information:
it has 1024 products in total.
There are around 405 potential customers in the neighborhood
Not everyone has visit the new Supermarket, and I know that in a group
of around 25 just 1 has gone and he has purchased 58 different products
(it does not matter how many of each of those products he purchased)
during that time.
I also know that other supermarket in the area, which has been in
business for 3 years, has sold around 488 products during that time.
There is a correct answer to this question, but I am looking for your
best guess, because obviously it is impossible to reach the correct one
(at least you are really lucky).
The answer that I need it is the quantity of products that has been sold
at least once (it does not matter that if the same product has been
solved 100 times, it is just count as 1).

It is probable that there is some overlapping in the purchases, example: most of the customers purchased Milk, and this counts just as 1 product sold, so I think that it is improbable that all products (1024) has been sold at least once

Answer 1

Do your own homework!

Answer 2

if you assume 1/25th of the population is going to buy at the store.
if you assume that 58 different products purchased is an average

Then
405/25*58=939.6
partial products are not allowed, so truncated = 939

Now, assuming we cant rely on the previous assumptions :)
if you assume the you will get the percentage of the total population/products bought shopping in your new store as was in the example store

488/405 = 1.205 average product per person
1 person out of a sample of 25 has bought 58 different products
58/25 = 2.32 average product per person
488*2.32=1132.16 which is over 1024, truncated to 1024

But maybe these assumptions are wrong too, how about:
if we assume that the previous supermarket has a smaller potential client base but will have a similar ration of products per client and we assume that 1.5 is a good average product per person (which is a guess ), then
488/1.5=325 potential clients for the current store
405*1.5=607.5 truncated to 607

So I guess 607 (since 1024 and 940 were already guessed)

Answer 3

1024

Answer 4

116

Answer 5

940 items that's really my best guess.
