The sum of three different positive integers is 11.
Which two of the following statements together provide sufficient information to determine the three integers?
Indicate two such statements.
A None of those three can be 1
B None of those three can be 4
C None of those three can be 7
D None of those three can be 8
Assuming all values are taken from (1 2 3 4 5 6 7 8 9 10),
First exclude 10 and 9, because the remaining two numbers must be different positive numbers, 1/1 will not work, and 1/0 will not work.
That leaves (1 2 3 4 5 6 7 8), of which you can only choose one among (5 6 7 8) and two among (1 2 3 4).
(1 2 3 4 | 5 6 7 8)
Then if two are excluded from (1 2 3 4), there will be only two values left, and the remaining one will be determined.
So choose "No 1" and "No 4".
