Sorry for my English, just trying my best. Double-digit number is, lets say, XY.

XY / X+Y = quotient 4 and remainder 3. I think that means xy = 4(x+y) + 3.

Now we have to divide(I guess?) the same number. If so, 4(x+y) + 3 / x*y = quotient 3 and remainder 5.

I dunno, if I got it right ;\ Answer is: 23. But how do I get that? Can you help me?
