Very typical number for the great battles of the era. This was Alexander's great rampaging army after all, I'm not sure why you think his army shouldn't be on par with Hannibal's.

The 50k number was in reference to Porus' army. Allegedly, Alexander was outnumbered between 3 and 5 to 1.

As another basis of comparison, both sides at the battle of Waterloo also fielded about 50k infantry a piece.
