Question

A number of aliens, who have dropped in from another planet,emerge from their spacecraft.

1. There is more than one alien
2. Each alien has the same number of fingers
3. Each alien has at least one finger on each hand.
4. The total number of fingers of all aliens is between 200 and 300.
5. If I knew the total number of fingers of all aliens, you would know how many aliens there are.

Answer 1

is there a question here?

Answer 2

How many hands does each alien have?

Answer 3

If doesn't matter. Different aliens can have different numbers of hands, and each alien can have different numbers of fingers on each of their hands, so long as the total number of fingers per alien is the same.

Answer 4

Still don't know what the question is :)

Answer 5

think the "each hand" in (iii) implies the number of hands is >1 and therefore n>1.

Answer 6

How many aliens are there?

Answer 7

a = number of aliens, f = number of fingers per alien, h = hands per alien, f(t) = total fingers.
a > 1
f >= 1
h >= 1
200 <= f(t) <= 300, unless by "between" you mean
200 < f(t) < 300?

If there are 200 fingers then
2 <= a <= 200.

If there are only 2 aliens with 100 fingers each then they satisfy all questions except 5.
1. >1 alien, Yes.
2. same # of fingers. Yes.
3. At least 1 finger per hand. Yes.
4. 200 to 300 fingers. Yes.
5. This is a bit dicy. Just knowing f(t) does not mean we know a. We need f(t) as well as f.

I don't think the 4 statements given can help us to know the number of aliens if we know the total number of fingers.

Answer 8

To me it reads more like a question to decide whether point #5 is a true or false statement. Is it really asking about the number of aliens?

Answer 9

I agree with istvan

Answer 10

yeah its asking about the number of aliens. I just assumed a range of aliens depending on the amount of fingers for each alien.
