Directions: Study the following table carefully and answer the questions given below it.

The number of students appeared and qualified in an exam (in million) from 5 different provinces in 6 different years.

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

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

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

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

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 %

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