  1. In which year the difference between the appeared students and the qualified students from province B was maximum?

    1. 2015
    2. 2016
    3. 2017
    4. 2018


Answer: (a) 2015

Solution: The difference between the appeared students and qualified students from province B in different years. $$ 2015 = 4.6 - 2.8 = 1.8 $$ $$ 2016 = 4.2 - 3.1 = 1.1 $$ $$ 2017 = 4.1 - 3.0 = 1.1 $$ $$ 2018 = 5.2 - 3.8 = 1.4 $$ $$ 2019 = 5.5 - 4.1 = 1.4 $$ $$ 2020 = 6.2 - 5.1 = 1.1 $$ Hence in 2015 the difference between the appeared students and the qualified students from province B was maximum.

  1. From which province was the total number of students, who qualified for the exam, the third-lowest in the year 2019 and 2020 together?

    1. A
    2. B
    3. C
    4. D


Answer: (b) B

Solution: Qualified students from different provinces in the year 2019 and 2020 together. $$ A = 4.8 + 5.8 = 10.6 $$ $$ B = 4.1 + 5.1 = 9.2 $$ $$ C = 4.2 + 4.8 = 9.0 $$ $$ D = 5.0 + 5.2 = 10.2 $$ $$ E = 3.2 + 4.2 = 7.4 $$ Hence the total number of students who qualified for the exam, the third-lowest in the year 2019 and 2020 together was from province B.

  1. What is the average number of students, appeared from province C over all the years together?

    1. 5.18 million
    2. 5.35 million
    3. 5.41 million
    4. 5.51 million


Answer: (a) 5.18 million

Solution: The total number of students appeared for the exam from province C over all the years together = 31.1 million.

Required average $$ = \frac{31.1}{6} $$ $$ = 5.18 \ million $$

  1. What was the ratio of the number of students who appeared from province A in the year 2019 to the number of students qualified from province E in the year 2017?

    1. 24 : 7
    2. 28 : 9
    3. 29 : 11
    4. 31 : 12


Answer: (d) 31 : 12

Solution: Required ratio $$ = \frac{6.2}{2.4} $$ $$ = 31 : 12 $$

  1. The number of students who qualified for the exam from province B in the year 2016 was approximately what percent of the number of students who appeared from province C in the year 2017?

    1. 58 %
    2. 62 %
    3. 67 %
    4. 72 %


Answer: (c) 67 %

Solution: Required percentage $$ = \left[\frac{3.1}{4.6} \times 100\right] \ \% $$ $$ = 67.39 \ \% $$ $$ \approx 67 \ \% $$
