Let n be the 3-digit number, and the value of the number.
Placing a 4 at the end of that 3-digit number turns it into
a 4-digit number whose value is 10n%2B4 .
If doing that incleases the value by 4828, then
10n%2B4-n=4828--->9n%2B4=4828--->9n=4828-4--->9n=4824--->n=4824%2F9--->highlight%28n=536%29 .
