Answer:
394
Explanation:
The largest number is 100 since it says none greater than 100. We can have 100
The next number is 99 since it is not equal to 100 and is the next largest number
The next number is 98 since it is not equal to 100 or 99 and is the next largest number
The last number is 97 since it is not equal to 100 or 99 or 98 and is the next largest number
The sum of the 4 numbers is
100+99+98+97 =394
