    In 1967 if another 5% of the population had been eligible to vote, 2.50 million more votes would have been cast, assuming the same voter turnout. How many million votes were caste in 1967?

    Solutions

    Let the population in -1967 be P.

    Now, from the question, (0.80 x 0.50 - 0.75 x 0.50) P = 2.50

    or, P = 2.50/0.025 = 100 million

    Number of votes cast in 1967 

    = 0.75 x 0.50 x 100 = 37.50 million

    If population in 1962 was 500 million, how many million votes did party X not get?

    Solutions

    Number of people eligible to vote

    = (0.70 × 500) 350 million

    Voter turnout = (0.60 × 350) = 210 million

    ∴ votes not polled for party X

    = (100 - 45)% of 210 = 55% of 210 

    = 115.50 million

    If the voter turnout in 1989 and votes polled for party X in 1980 were the same, then find the ratio of the population in 1980 to that in 1989.

    Solutions

    Let the population in 1980 and 1989 be P1 and P2 respectively.

    Number of votes polled for party X in 1980

    = P1 × 0.75 × 0.40 × 0.60

    Voter turnout in 1989 P2 × 0.80 × 0.30

    Now, P1 × 0.75 × 0.40 × 0,60 = P2 × 0.80 × 0.30
