General Election Results analysis for party P1
Year Percentage of population eligible to vote Voters turnout % Percentage of votes casted for party P1
1962 60 70 45
1967 50 75 40
1971 45 80 48
1977 55 60 50
1980 40 75 60
1984 52 78 50
1989 30 80 35
If population of the state in the year 1977 was 800 million, then how many people voted for party P1 in the year 1977?
» Explain it
Number of people to eligible vote = 55% of 880 = 440 million
Voters turnout = 60% of 440 = 264 million
Number of people who voted for party P1 = 50% of 264 = 132 million
Hence, option B is correct.
Between 1984 and 1989 the number of people eligible to vote increased by 20%. Find the percentage increase in the population?
» Explain it
Let, the population in 1984 and 1989 be x any y respectively

Number of people eligible to vote in 1984 = 0.52x

Number of people eligible to vote in 1989 = 0.30y

According to the question,

0.30y – 0.52x  = 0.20 ; y = 2.08x

% increase in population =  y – x  × 100 = 108%

Hence, option D is correct.

In 1967, if another 5% of the population had been eligible to vote, 24 million more people would have voted, assuming the same voters turnout percentage. How many people actually voted in 1967?
» Explain it
Let the population of the state be ‘x’ in 1967
Number of people who voted in 1967 = x (0.5) (0.75)
According to question,
x (0.55) (0.75) – x (0.5) (0.75) = 24000000
x = 640000000
Number of people who voted in 1967 = 240000000
Hence, option C is correct.
If population of the state in 1962 was 500 million and every year population of the state increases by 10 million, what is the average number of people voting for party P1 in every election from 1962 to 1977?
» Explain it
Population in 1962 = 500 million
Number of people voting for party P1 in 1962 = 60% of 70% of 45% of 500 = 94.5 million
Population in 1967 = 550 million
Number of people voting for party P1 in 1967 = 50% of 75% of 40% of 550 = 82.5 million
Population in 1971 = 590 million
Number of people voting for party P1 in 1971 = 45% of 80% of 48% of 590 = 101.952 million
Population in 1977 = 650 million
Number of people voting for party P1 in 1977 = 55% of 60% of 50% of 650 = 107.25 million
Therefore, required average = 96.5505 million
Hence, option D is correct.
If the voters turnout in 1989 and the number of people who voted for party P1in 1980 were the same, then find the ratio of the population in 1980 to that of population in 1989?
» Explain it
Let the population in 1980 and 1989 be u and v respectively
Number of who voted for party P1 in 1980 = u × 0.75 × 0.40 × 0.60
Voters turnout in 1989 = v × 0.80 × 0.30
u × 0.75 × 0.40 × 0.60 = v × 0.80 × 0.30
u  =  4
v 3

Hence, option B is correct.
