    On the basis of given table in question ,
    Difference in production of toys of type B and C :
    Year 2002 ⇒ 150 – 78 = 72 thousand
    Year 2003 ⇒ 180 – 100 = 80 thousand
    Year 2004 ⇒ 175 – 92 = 83 thousand
    Year 2005 ⇒ 160 – 120 = 40 thousand
    Year 2006 ⇒ 185 – 130 = 55 thousand
    Total difference in production of toys of type B and C = 72 + 80 + 83 + 40 + 55 = 330 thousands
    Number of types of toys = 5

    Correct Option: B

    On the basis of given table in question ,

    According to given table, we have
    Total production of toys in 2005 = 675 thousand
    Total production of toys in 2006 = 750 thousand
    Increase = 750 - 675 = 75 thousand

    Percentage increase =
    Increase
    		 × 100 = 11%
    675

    Correct Option: C

    According to given table, we have
    Total production of toys in 2005 = 675 thousand
    Total production of toys in 2006 = 750 thousand
    Increase = 750 - 675 = 75 thousand

    Percentage increase =
    Increase
    		 × 100 = 11%
    675

    Percentage increase =
    75
    		 × 100 = 11%
    675

Direction: A survey of movie going habits of city dwellers from 5 cities A, B, C, D and E is given below. The first column gives the percentage of viewers in each city who watch less than two movies a week. The second column gives the total number of viewers who view two or more movies per week. Study the table and answer the questions.

  1. Which two cities have the same number of movie watchers?








  1. View Hint View Answer Discuss in Forum

    On the basis of given table in question ,
    Let total number of film watchers be 100% .
    In city A , If 60% of them watched less than two movies a week , then 40% watched two or more movie per week .
    ∴ 40% ≈ 2400

    ⇒ 1% =
    2400
    40

    Now , 100% =
    100 × 2400
    		 = 6000
    40

    Similarly for city B,
    ⇒ 100% =
    100 × 3000
    		 = 3750
    80

    For city C,
    ⇒ 100% =
    100 × 2400
    		= 16000
    15

    Correct Option: D

    On the basis of given table in question ,
    Let total number of film watchers be 100% .
    In city A , If 60% of them watched less than two movies a week , then 40% watched two or more movie per week .
    ∴ 40% ≈ 2400

    ⇒ 1% =
    2400
    40

    Now , 100% =
    100 × 2400
    		 = 6000
    40

    Similarly for city B,
    ⇒ 100% =
    100 × 3000
    		 = 3750
    80

    For city C,
    ⇒ 100% =
    100 × 2400
    		= 16000
    15

    For city D,
    ⇒ 100% =
    100 × 2700
    		 = 6000
    45

    For city E,
    ⇒ 100% =
    100 × 8000
    		 = 32000
    25

    Hence , A and D cities have the same number of movie watchers , which is 6000 .
