If he had to lower it by 25%, it currently weight 75% of its original weight so if we let w=original weight:
w(75/100)=30 multiply both sides by 100
75w=3000 divide both sides by 75
w=40
So the original weight of the luggage was 40 kilograms.

<em>Additional comment</em>
The expression |x| means "the absolute value of x". It is the value of x with the sign made positive. That is |-10| = 10, a number greater than 9. Of course, |13| = 13, also a number greater than 9.
