August Trivia Question & June Trivia Answer

June Trivia Problem

In a town of Sun City, a rich aristocrat decided that he would give every man $45 and every woman $60.

Only one ninth of the men and only one twelfth of the women collected their dues.

Can you tell how much money the aristocrat spent if there were 3552 people in total?

June Solution

Let the number of men =x
and number of women =y
then, x + y =3552
$45 for every men and $60 for every women
but 1/9 of x took the money
and 1/12th of y took the money
therefore total amt spent =45*(x/9)+ 60*(y/12)
= 5(x+y)
=5*3552
=17760 total amt spent

What is the original number if all digits are different?
