  1. View Hint View Answer Discuss in Forum

    Required percentage =The number of persons killed in coal mines in 2006 X 100%
    The number of persons killed in industrial accidents in 2006

    Correct Option: B

    As per given graph , we can see that
    The number of persons killed in coal mines in 2006 = 300
    The number of persons killed in industrial accidents in 2006 = 1200

    ∴ Required percentage =The number of persons killed in coal mines in 2006 X 100%
    The number of persons killed in industrial accidents in 2006

    ∴ Required percentage =300 X 100% = 25%
    1200

Direction: Study the information given in each of these questions and then answer the questions.

  1. View Hint View Answer Discuss in Forum

    Average female population =sum of total numbers of females
    total number of cities

    Correct Option: A

    From above given table , we can see that
    The total population of all cities = 12 + 15 + 17 + 19 + 22 = 85 million
    Total males in all cities = 6.5 + 7.2 + 9.0 + 9.9 + 10.8 = 43.4 million
    Total females = 85 – 43.4 = 41.6 million

    Average female population =sum of total numbers of females
    total number of cities

    = 41.6 = 8.32 million

  1. The area of the circle is 616 cm2. What is the area of the rectangle?












  1. View Hint View Answer Discuss in Forum

    ∵ Area of the circle = πr2
    Required Area of the rectangle = Length x Breadth

    Correct Option: C

    given :- Area of the circle = 616
    ⇒ πr2 = 616
    Put the value of π = 22/7 in above equation.
    we will get,
    ⇒ r2 = 196
    ⇒ r = 14 cm
    Length of the rectangle = Diameter of the circle = 2r
    Breadth of the rectangle = Radius of the circle = r
    ∴ Area of the rectangle = Length x Breadth
    ∴ Area of the rectangle = 28 × 14 = 392 cm2

  1. What is the precentage of electrified villages in the state (A)?










  1. View Hint View Answer Discuss in Forum

    Percentage of electrified villages in the state A = 100 - 25 .

    Correct Option: D

    Percentage of electrified villages in the state A = 100 - 25 = 75%

  1. In which of the following states percentage of electrified villages is double the percentage of electrified villages in state (D)?










  1. View Hint View Answer Discuss in Forum

    Percentage of electrified villages in state D = 100 - 60
    Percentage of electrified villages in state C = 100 - 20

    Correct Option: A

    Percentage of electrified villages in state D = 100 - 60 = 40
    Percentage of electrified villages in state C = 100 - 20 = 80
    Hence, the percentage of electrified villages in the state C is double the percentage of electrified villages in state D.
