    From the given bar diagram , we see
    Number of CD produced by the company in 2008 = 25000
    Number of pen-drives produced by the company in 2008 = 30000
    Total number of CD and pen-drives produced by the company in 2008 = 25000 + 30000 = 55000
    Number of keyboards produced by the company in the year 2006 = 15000
    Required difference = Total number of CD and pen-drives produced by the company in 2008 - Number of keyboards produced by the company in the year 2006

    Correct Option: D

    From the given bar diagram , we see
    Number of CD produced by the company in 2008 = 25000
    Number of pen-drives produced by the company in 2008 = 30000
    Total number of CD and pen-drives produced by the company in 2008 = 25000 + 30000 = 55000
    Number of keyboards produced by the company in the year 2006 = 15000
    Required difference = Total number of CD and pen-drives produced by the company in 2008 - Number of keyboards produced by the company in the year 2006
    ∴ Required difference = 55000 - 15000 = 40000

    According to given bar graph , we have
    Total number of all products produced in 2006 = ( 10 + 7.5 + 15 ) × 1000 = 32.5 × 1000 = 32500
    Total number of all products produced in 2008 = ( 25 + 30 + 20 ) × 1000 = 75 × 1000 = 75000

    Correct Option: A

    According to given bar graph , we have
    Total number of all products produced in 2006 = ( 10 + 7.5 + 15 ) × 1000 = 32.5 × 1000 = 32500
    Total number of all products produced in 2008 = ( 25 + 30 + 20 ) × 1000 = 75 × 1000 = 75000
    Total number of all products produced in 2006 and 2008 together = 32500 + 75000 = 107500

Direction: Study the bar diagram and answer the given questions.

  1. Ratio of highest and lowest marks obtained in first term among all the subjects is








  1. View Hint View Answer Discuss in Forum

    According to given bar graph , we have
    Highest marks obtained in first term subject = 100 ( Math )
    Lowest marks obtained in first term subject = 70 ( English )
    Required ratio = Highest marks obtained in first term subject : Lowest marks obtained in first term subject

    Correct Option: C

    According to given bar graph , we have
    Highest marks obtained in first term subject = 100 ( Math )
    Lowest marks obtained in first term subject = 70 ( English )
    Required ratio = Highest marks obtained in first term subject : Lowest marks obtained in first term subject
    Required ratio = 100 : 70 = 10 : 7
