Hi @Anil R,
Hopefully you remember some basic math, namely what we call weighted average. To answer your query, their combined average will be the weighted average by impressions. Giving you a numerical example for easier understanding.
Their combined Average Position is calculated as follows:
Avg Pos = (2.0*30 + 3.0*20) / (30+20) = 120/50 = 2.4
The result (2.4) is the weighted average of 2.0 and 3.0 where the weights are the counts of impressions, i.e. 30 and 20.
