The largest possible sum of 4 unequal numbers, none greater than 100, is A. 380 B. 388 C. 390 D. 394

394

Step-by-step 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
