I am a bit confused now. Let me show you my work. With 15 integers, the median would be 8th number in that row. S(1): Exactly seven of the numbers are greater than 7 Case 1: 7,7,7,7,7,7,7,7,9,10,11,12,13,14,15 --> Median is 7 Case 2: 1,2,3,4,5,6,7,7,9,10,11,12,13,14,15 --> Median is 7 S(2): Exactly ...

If 5 percent of the personnel stationed at army base M are officers, how many of the personnel stationed at army base M are not officers?

1) 15 percent of the officers at army base M are women.
2) 65 percent of the women employed at army base M are officers

OA is E

mn + 2m + n + 1 is even
Only one case make it even --> e*o + e + o + o
m = even
n = odd

(i) (2*odd + e)^2 = even
(ii) (odd)^2 + 2(odd) - odd = even
(iii) (even)^2 - 2(even)(odd) + (odd)^2 = odd

Hence answer is E
