Question

Find two digit number( or the sum of those numbers) in which when changing the numbers, the number will be decreased by 28,125%.

Answer 1

((10x+y) - (10y+x))/(10x+y) = 0.28125

Answer 2

looks like i should go for programming solution than algebraic solution

Answer 3

Algebraic would be needed.

Answer 4

decrease by 28.125% means new number will be 575/800 times old number.
so, using experimentX's symbols:\[\frac{575}{800}(10x+y)=10y+x\]multiplying out and simplifying will lead to:\[y=\frac{2}{3}x\]you should be able to now work out all the required values.
