The Mapusaurus may be outnumbered and have a lower combined weight, but they still have the height advantage to take down the Purussaurus with.

[dinosauria101]

I think the Mapusaurus can narrowly pull this off as well.
At max (3 of MCF-PVPH-108.145 vs 5 of UFAC 1403) especially, the weight disadvantage is less and they have superior stamina and agility. Not to mention, if 2 Mapusaurus can kill a Purussaurus fast enough before the 3rd is killed, that would favor them further still.

[DonaldCengXiongAzuma]

The mapusaurus which are heavier in weight and more agile on land can win.

[dinosauria101]

I do believe it's the Purussaurus that are actually heavier together - 31 vs 25.5 at max.

That said, I agree the Mapusaurus win for the other reasons.
