Double-digit number is divided by its number total = quotient 4 and remainder 3. If we divide the same number by its figures product, we get a quotient 3 and remainder 5. What is that double-digit number?
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?
No, you should say that the digits are X and Y and hence, the number becomes 10X + Y
Hence, for the first statement, you get:
and R = 3
And the second statement:
and R = 5
You have 2 equations and 2 unknowns, find X and Y.
EDIT: Again, too late XD
