Solution:

We are given that when positive integer x is divided by positive integer y, the quotient is 17 and the remainder is 3. Thus:

x/y = 17 + 3/y

x = 17y + 3

We are also given that when x is divided by (y−3), the quotient is 24 and the remainder is 5. Thus:

x/(y-3) = 24 + 5/(y-3)

x = 24(y-3) + 5

x = 24y - 72 + 5

x = 24y - 67

We can equate our two equations and we have:

17y + 3 = 24y - 67

70 = 7y

y = 10

Thus, x = 17(10) + 3 = 173.
