Is the median of 7 different integers less than 15?
(1) The largest number is 18
(2) The least number is 12

Medium difficulty I would say.

so if we were to rephrase, the question is asking if the 4th element in the set is less than 15? (keeping in mind that the integers will be different)

i go for B

1) we know the 7th number in the set is 18 but we do not know the range,
so it could be {2, 3, 7, 15, 16, 17, 18} which is not less than 15 OR it could be {2, 3, 7, 8, 10, 17, 18} which is less than 15

2) we know the 1st number is 12 and the integers have to be different, so the extreme would be 12, 13, 14, 15... which means that the median will not be less than 15.

please correct me if my logic is incorrect :)

Didn't saw that - why not (C) ?

since median can be 15 or more/less in either (A) or (B).

Thanks
