Answer:
loser received 3000 votes
Step-by-step explanation:
given the ratio of votes was 7 : 5
The 7 part of the ratio, relates to the 4200 votes
dividing this by 7 gives the value of one part of the ratio
4200 ÷ 7 = 600 ← value of 1 part of the ratio , then
5 parts = 5 × 600 = 3000
That is the loser received 3000 votes
