    See the chart and compare the graph.

    Correct Option: C

    Obvious from the chart , we can say that 1998–1999 year has the same import and export.

Direction: Study the following table carefully and answer the question given below it.

    As we can see in the graph that metropolises location has continuous increase both in appeared and passed.

    Correct Option: D

    As we can see in the graph that metropolises location has continuous increase both in appeared and passed.

    Our intelligent observation says that the required year cannot be 1993, 1994, 1995. Why? Because see the following conclusions:
    % passed to appear = Passed / Appeared x 100
    % of passed to appear is least when Passed / Appeared is the least or, Appeared / Passed is the most.

    Correct Option: C

    Our intelligent observation says that the required year cannot be 1993, 1994, 1995. Why? Because see the following conclusions:
    % passed to appear = Passed / Appeared x 100
    % of passed to appear is least when Passed / Appeared is the least or, Appeared / Passed is the most.
    Now, we do the further calculations mentally. See the following conclusions:
    For 1990: 7894 / 2513 ⇒ Quotient = 3 and Remainder ≈ 300
    For 1991: 8562 / 2933 ⇒ Q = 3 and R ≈ 400
    For 1992: 8139 / 2468 ⇒ Q = 3 and R ≈ 800
    Similarly, for 1993; 1994, 1995, Q is 2.
    So, 1992 gives the highest value.

  1. What approximate value was the percentage drop in the number of semi-urban candidates appeared from 1991 to 1992?

    Percentage drop = Semi-urban candidates appeared in 1991 - Semi-urban candidates appeared in 1992 × 100
    Number of semi-urban candidates appeared in 1991

    Correct Option: A

    Percentage drop = Semi-urban candidates appeared in 1991 - Semi-urban candidates appeared in 1992 × 100
    Number of semi-urban candidates appeared in 1991

    8562 - 8139 × 100 = 423× 100 ≈42 × 10 = 5 %
    8562856284

  1. In 1993 percentage of candidates passed to appeared was approximately 35 from which location?

    We do not need to calculate the values for each year.
    Follow as :
    For Rural area : 35% of 5032 ≈ 35 × 50 = 1750 ≈ 1798
    For Semi-urban area: 35% of 9500 ≈ 35 × 95 ≈ 3300

    Correct Option: E

    We do not need to calculate the values for each year.
    Follow as:
    For Rural area : 35% of 5032 ≈ 35 × 50 = 1750 ≈ 1798
    For Semi-urban area : 35% of 9500 ≈ 35 × 95 ≈ 3300
    Which cannot be approximated to 3500.
    For State capitals : 35 × 85 = 3000
    For Metropolises : 35 × 110 = 3850
