First, let's make some sense.
The subject matter "HELP!" does not.
This may happen that I'll be asked the same question twice.
Do I have to waste that much time?
The subject matter must be more relevant to your problem.
>COULD YOU PLEASE HELP ME?? I
>HAVE THE ANSWER BUT I
>DO NOT KNOW HOW MY
>FATHER GOT THE ANSWER?
Are you not on speaking terms with your father?
Perhaps he wants you to do some thinking. May
it be so?

Formula for what? Just stop to think for a moment before you pose a question.

A simple problem that requires a little creativity.

Well, let's try moving ahead.
First of all, you are looking for 5 different numbers. Is that clear? No 2 numbers may be the same. Try to justify this claim.
Imagine having written down the 10 equations and, subsequently, summing them up. What will be the right hand side? The left hand side will be interesting. It'll be 4 times the sum of the 5 unknown numbers. From here you'll be able to determine the sum -
Assume the 5 distinct numbers listed in the order of the magnitudes are a, b, c, d, e. Then a + b = 110. d + e = 121. From here and the sum being 289, c = 58.
a + b = 110. There are just two possibilities:
a = 54, b = 56, or
a = 53, b = 57.
d + e = 121. There are just two possibilities:
d = 60, e = 61, or
d = 59, e = 62
Just see, by trial and error, which ones work.
Let the numbers be a, b, c, d, e in the growing order: a is the smallest, e the largest.
