Mean = Total of the numbers / n
So total of the numbers = n*mean
The way to know the Prime Numbers is to find out if they can only Multiplied Once ,The way to know Composite Numbers is to find out if they can be Multiplied Twice
What's the question ? Is it to find what the two numbers are ? Since you know their average, you know what the sum of the two numbers is. It's double their average. Now you know their sum, and you know their product. Take the product, and list all of its factors. Find two of the factors that add up to the sum of the two numbers. Those are probably the two numbers you're looking for.
In general you cannot. You will need to know more about the distribution of the variable - you cannot assume that the distribution is uniform or Normal.
Do you know how to find the area of a circle when you know the radius ? Good! Do that. Do you know how to find the area of a square when you know the length of the side ? Good! Do that. Now you have two numbers ... the area of the circle and the area of the square. The problem wants you to find the difference of these two numbers. Do you know how to use subtraction to find the difference of two numbers ? Good! Do that.
There is no way to find B 160 50 and 120 without knowing what these numbers correspond with. Once we know what the numbers correspond with then we can find the answer.
To calculate population distribution, one must know the total of the population, as well as, the total area of the land in which the population is in. Then, the total population is divided by the total area. The population distribution is answered in square kilometers and square miles.

i dont even know
If both of your numbers divide into them evenly with no remainder, they are common multiples.
20 101 a three digit number and i don't know what is the answer

You cannot. Suppose the mean of a set of numbers is m. Now add the pair of numbers m-x and m+x to the set, where x is any number. The new, extended set will have the same mean as before but two more members.
In general, you cannot. You need to know how many numbers there are and then, in only a select few cases can you find the set.
