I hope I put this on the right section, it's about finding the x and y.

Question:

"X to Y is positive integer numbers, not negative ones.

7.5% within X to Y, contains number starting from 1440 to 1504.

X to 1440 shares 20% of the whole cake. The rest (72.5 %) is from 1504 to Y.

Find the X and Y."

Thank you very much for your good response.

PS: If this lacks of one or more thing, would you please define for which one is it?
