How do you calculate the total percentage of votes won by a party in two-round electoral systems?

If a party wins 24% in the first round and 36% in the second, what is the total percentage of votes it has collected ?



Thank you in advance.How do you calculate the total percentage of votes won by a party in two-round electoral systems?
It depends on how many people voted in the first and second rounds.



If an equal number voted both times, then you just average 24 and 36



(24 + 36) / 2 = 30%
