Question

Need Help for this extremely hard Math problem?

I am thinking of 5 numbers. Each combination of 4 numbers from those 5 has a product of either 10, 20, 30, 40, or 50. What is the quotient of the sum of all 5 numbers divided by the product of all 5 numbers?

Answer 1

Extremely hard?

Answer 2

yes

Answer 3

Do we know that those 5 products each occur, or are they simple the list of possible products?

Answer 4

i dont know

Answer 5

Do we know if the 5 numbers are unique?

Answer 6

No we don't know anything other then what the question asked

Answer 7

Well if 10 occurs, then it could be because 4 of the numbers are:
10 * 1 * 1 * 1
or
5 * 2 * 1 * 1

It could not be 10*1*1*1 because there is no 5th number that would ensure the products required for any 4 combo of numbers.

Nor could it be 5*2*1*1 because there is no 5th number that would work.

Answer 8

So 10 does not occur. Yay.
