Hint
It doesn't actually matter how many men or women there were.

Answer
17,760 dollars.

If there were M men, then there were (3552 − M) women.

So one ninth of the men each received 45 dollars and one twelve of the women each received 60 dollars. So the total received was:
= 45 x 1 x M  +  60 x  1 x (3552 − M)
       —              ——
       9              12

Simplify the two fractions by dividing the 45 by 9, and the 60 by 12 respectively.

= 5 x M + 5 x (3552 − M)

= 5M + 17760 − 5M

= 17760

Hint
A little bit of algebra might help.

Answer
I have 14 apples and you have 28 apples.

Reasoning
We can work this out with a little algebra. I have A apples and you have B apples, then
[1]  5 x (A − 7) = B + 7

[2]        A + 7 = B − 7

From [1] we have:

    5A − 35 = B + 7
[3]      5A = B + 42

From [2] we have:

[4]  A + 14 = B

We can then use [4] in [3] to give:

  5A = (A + 14) + 42
  5A = A + 56
  4A = 56
   A = 14

Which gives B = 28 (by [4]).
