It would help if you proofread your questions before you posted them.

How is "rounded to the nearest 100" different from "rounded to my hundreds digit"?

The first number must be 7 or 8.

Ones number must be even: 2, 4, 6 or 8.

758 would add to 20.

848 would add to 20.

Clarifying your problem for the tens digit might help you choose the right answer.
