Answer:
Total number of people who voted in the elections = 140.
Step-by-step explanation:
Votes received by Freda = 60%
So, the votes received by Sonja = (100 - 60)% = 40%
So difference between the votes of Sonja and Freda = 60% - 40% = 20%
Also Freda won by 28 votes, so difference between their votes = 28 votes
Let the total number of people voted = K
Now, according to the question
20 % of K = 28
⇒ K = 2800/20 = 140
So, the total number of people who voted in the elections are 140.
