Answer:

231

Explanation:

The sum of the digits is 6, and the tens digit is equal to the sum of the other two digits. That means the tens digit is half the sum of all three digits, so the tens digit is 3.

That leaves the sum of the units and hundreds digit being 3; and since the hundreds digit is twice the units digit, the units digit is 1 and the hundreds digit is 2.
