What is the ratio of the number of people who did not vote to the number of people who voted for the party in 2000?
145 : 42
Let the population be 100.
The number of people who did not vote = 30 + ((25)×70) = 58
Number of people who voted for the party = 100 × (70100) × (35) × (25)
So the required ratio = 145 : 42
