### Divisional Math Olympiad, Dhaka-2016,primary, ques. 7

x is a two-digit positive number and y is a three digit positive number
The values of x and y is such that if x is added by y % and if y is subtracted by x %, the result will be the same
How many numbers can be replaced with x or y such that the above statement is true???

I didn't understand why are we taking $99$ to prove the problem

Because $x$ has the only value $99$.

Solve.
X = 99 and Y = 100
Because,
x*y% = 99*100% = 99 and y*x% = 100*99% = 99

Sorry, my answer was wrong. Can you solve this?
