Question

Let x, y and z be distinct positive integers
satisfying x<y<z and x + y + z = k. What
is the smallest value of k that does not
determine x, y and z uniquely?
(1) 9
(2) 7
(3) 10
(4)8​

Answer 1

Answer:

the smallest number in the options is 7.

so let's work with seven.

7 can be expressed as 4+2+1

you try any other combination, it won't be unique

let's try 8

8=5+2+1

8=4+3+1

so you have more than 1 combination for 8

so the solution cannot be determined uniquely for the given condition.

so 8 is the answer
