    From the given bar diagram , we see
    Total population of the state in 2004 = 5 lakhs
    Total percent of Hindu and Muslim population of the state in 2004 = 30 + 25 = 55%
    Total ( Hindus + Muslims ) population in 2004 = 55% of 5 lakhs

    Correct Option: B

    From the given bar diagram , we see
    Total population of the state in 2004 = 5 lakhs
    Total percent of Hindu and Muslim population of the state in 2004 = 30 + 25 = 55%
    Total ( Hindus + Muslims ) population in 2004 = 55% of 5 lakhs

    Hindus + Muslims =
    500000 × 55
    		= 275000

    According to given bar graph , we have
    The Hindu population in 2004 = 30%
    And Sikh population in 2004 = 45%
    Required ratio = The Hindu population in 2004 : Sikh population in 2004

    Correct Option: C

    According to given bar graph , we have
    The Hindu population in 2004 = 30%
    And Sikh population in 2004 = 45%
    Required ratio = The Hindu population in 2004 : Sikh population in 2004
    ∴ Required ratio = 30 : 45 = 2 : 3
