1) Set Q consists of consecutive even integers and set P of consecutive odd integers.

2) The median of set Q is higher than the mean of set P.

According to 1st

let's Q = {2,4,6,8,10,12,14}
so P = {1,3,5,7,9,11,13,} OR
P = {3,5,7,9,11,13,15}

1st is insufficient.

According to 2nd, the median of Q is higher than the mean of P. It still is inconclusive.

2nd if insufficient.

However, if we combine both the statements, we'll see that P = {1,3,5,7,9,11,13}. hence C.
