This is actually an easy problem - just book-keeping involved.

I'll do a different - but similar - problem for you:

15% more than 5% less than x is what percent of 40x ?

5% less than x = 0.95 * x

15% more than 5% less than x = 1.15 * 0.95 * x

15% more than 5% less than x is what percent of 40x = (1.15 * 0.95 * x)/(40*x) * 100 % = 2.73 %

Re: HIGH LEVEL PROBLEM !!

Hello, sehs!

Are you sure the problem said "of 10x" ?

10% more than 10% less than x is what percent of 10x ?

This is a variation of a classic "trick question."

Your boss says, "Business is slow this season, so I'm asking you to take a 10% cut in salary for
the next four months. At the end, I'll give you a 10% raise so you're back to your original salary."

This, of course, is a blatant lie . . .

Suppose your salary is $1,000 per week.
A 10% cut means: .\(\displaystyle 10\% \times 1,000 \:=\:100\) dollars less.
So your new salary is: \(\displaystyle \$1,000 - 100 \:=\:\$900\)

Then you are given a 10% raise.
This means: .\(\displaystyle 10\% \times 900 \:=\:90\) dollars more.
And your "restored" salary is: \(\displaystyle \$900 + 90 \:=\:\$990\)

So you will be making less than your original salary.

my problem and solution was:
