    Profit in 1982

    Required percentage increase =
    15
    × 100 = 150%

  1. The ratio of the average income of all the years to the average profit is









  1. View Hint View Answer Discuss in Forum

    From the given bar diagram , we see
    Total profit of all the years = 10 + 20 + 10 + 20 + 25 = 85
    Number of years = 5

    Average profit = $ 10 + 20 + 10 + 20 + 25 lakhs
    5

    Correct Option: B

    From the given bar diagram , we see
    Total profit of all the years = 10 + 20 + 10 + 20 + 25 = 85
    Number of years = 5

    Average profit = $ 10 + 20 + 10 + 20 + 25 lakhs
    5

    Average profit = $ 17 lakh
    ∴ Average income = $ 48 lakh
    Required ratio = Average income : Average profit
    Required ratio = 48 : 17
