  1. The export to Hongkong is approximately how many times the exports to Germany?








  1. View Hint View Answer Discuss in Forum

    According to given bar graph , we have
    The export to Hongkong = 10.6
    The export to Germany = 1.2

    ∴ Required answer =
    The export to Hongkong
    The export to Germany

    Correct Option: C

    According to given bar graph , we have
    The export to Hongkong = 10.6
    The export to Germany = 1.2

    ∴ Required answer =
    The export to Hongkong
    The export to Germany

    ∴ Required answer =
    10.6
    		≈ 10
    1.2

  1. The ratio of the total exports to Japan, Belgium and Hongkong to the export to rest of the countries in 1991–92 is nearly :

    From the given bar diagram , we see
    Total exports to Japan, Belgium and Hongkong = 12.5 + 12.1 + 10.6 = 35.2
    Total exports = $ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 69.6 billion
    Total exports of remaining countries = 69.6 - 35.2 = 34.4
    Required ratio = Total exports to Japan, Belgium and Hongkong : Total exports of remaining countries

    Correct Option: A

    From the given bar diagram , we see
    Total exports to Japan, Belgium and Hongkong = 12.5 + 12.1 + 10.6 = 35.2
    Total exports = $ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 69.6 billion
    Total exports of remaining countries = 69.6 - 35.2 = 34.4
    Required ratio = Total exports to Japan, Belgium and Hongkong : Total exports of remaining countries
    ∴ Required ratio = 35.2 : 34.4 ≈ 35 : 34

  1. The country to which twice the export is nearly equal to the average exports in 1991–92 is

    According to given bar graph , we have
    Total exports = $ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 69.6 billion
    Number of countries = 10

    ∴ Average exports =
    Total exports
    Number of countries

    table>∴ Average exports =
    69.6
    = $ 6.96 billion 10

    Correct Option: D

    According to given bar graph , we have
    Total exports = $ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 69.6 billion
    Number of countries = 10

    ∴ Average exports =
    Total exports
    Number of countries

    table>∴ Average exports =
    69.6
    = $ 6.96 billion 10
    Exports to UAE = $ 3.3 billion
    Hence , required answer is UAE .

  1. The ratio of the sum of the exports to the bottom six countries to the total exports to all the given countries in 1991 – 1992 is approximately :

    On the basis of given graph in question ,
    Total exports = $ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 69.6 billion
    Total exports to bottom six countries = $ (3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 11.8 billion

    Required Ratio =
    Total exports to bottom six countries
    Total exports

    Correct Option: A

    On the basis of given graph in question ,
    Total exports = $ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 69.6 billion
    Total exports to bottom six countries = $ (3.3 + 2.5 + 1.6 × 3 + 1.2) billion = $ 11.8 billion

    Required Ratio =
    Total exports to bottom six countries
    Total exports

    ∴ Required Ratio =

    From the given bar diagram , we see
    Total foreign exchange reserves = 2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120
    Total number of years = 8

    Average foreign exchange reserves =
    (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120)
    		million dollar
    8

    Average foreign exchange reserves = 27840 million dollar
    8

    Correct Option: C

    From the given bar diagram , we see
    Total foreign exchange reserves = 2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120
    Total number of years = 8

    Average foreign exchange reserves =
    (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120)
    		million dollar
    8

    Average foreign exchange reserves = 27840 million dollar
    8

    Average foreign exchange reserves = 3480 million dollar
    Years that have more than average foreign exchange reserves ⇒ 2007, 2011, 2012
    Number of the foreign exchange reserves above the average = 3
    Number of the foreign exchange reserves below the average = 5
    Required ratio = 3 : 5
