Is the sum of 5 different positive integers greater than 35?
(1) The median number is 10.
(2) The largest number is 12.


The oa is A. Here when median is 10, the no.s can be 1,2,10,11,12 when the sum is >35. But at the same time the no.s can be 1,1,10,11,11. In this case the sum in not >35 and we can not get the ans. Any takes on this.. [spoiler].The OA can not be B . Because 12 is the largest no and no idea about last 4 no.s[/spoiler]

The median number is 10 so we have _ _ 10 _ _
We want the smallest one sum, it is 1 2 10 11 12
The sum of this one is 36, so we can answer the question with 1)
1 2 10 11 11 is not accepted by the question given they are 5 different positive integers
(2) The largest number is 12.
Insufficient

So A
