Median of 12 > Median of 10 ??

Statement 1: Insufficient. We do not know the average/median of weights. The average can be greater than median and vice versa. Both situations possible

A D / B C E

Statement 1: Sufficient. The weight of 2 dogs is more than the median of other 10. Surely, there will be a increasing shift of Median.

'B' is the winner.

Answer is E definitely.
Old median could be mode, thus even the shift cause median to remain same. This may or may not be the case. Hence insufficient.
