Data Interpretation (UPSC)

21. Which region/regions of the curve correspond/corresponds to incubation phase of the infection? [2011-1]

Read the passage given below, study the graph that follows and answer the three items given below the figure.

During a party, a person was exposed to contaminated water. A few days later, he developed fever and loose motions. He suffered for some days before going to a doctor for treatment. On starting the treatment, he soon became better and recovered completely a few days later. The following graph shows different phases of the person's disease condition as regions A, B, C, D and E of the curve.

(a) A only
(b) B only
(c) B and C
(d) No part of the curve indicates the incubation phase

Correct Answer: (a) A only
Note:

Incubation phase means the time between somebody being infected with a diseases in graph part A shows that phase.

22. Which region of the curve indicates that the person began showing the symptoms of infection? [2011-1]

Read the passage given below, study the graph that follows and answer the three items given below the figure.

During a party, a person was exposed to contaminated water. A few days later, he developed fever and loose motions. He suffered for some days before going to a doctor for treatment. On starting the treatment, he soon became better and recovered completely a few days later. The following graph shows different phases of the person's disease condition as regions A, B, C, D and E of the curve.

(a) A
(b) B
(c) C
(d) D

Correct Answer: (b) B
Note:

Region B clearly shows the symptoms of infection.

23. Which region of the curve indicates that the treatment yielded effective relief? [2011-1]

Read the passage given below, study the graph that follows and answer the three items given below the figure.

During a party, a person was exposed to contaminated water. A few days later, he developed fever and loose motions. He suffered for some days before going to a doctor for treatment. On starting the treatment, he soon became better and recovered completely a few days later. The following graph shows different phases of the person's disease condition as regions A, B, C, D and E of the curve.

(a) C
(b) D
(c) E
(d) The curve does not indicate the treatment

Correct Answer: (c) E
Note:

Though relief began from region C but only region E indicates effective relief.

24. Consider the following distance - time graph. The graph shows three athletes A, B and C running side by side for a 30 km race. [2011-1]

With reference to the above graph, consider the following statements:

1. The race was won by A.

2. B was ahead mark of A up to 25 km mark

3. C ran very slowly from the beginning.

Which of the statements given above is/are correct?

(a) 1 only
(b) 1 and 2 only
(c) 2 and 3 only
(d) 1, 2 and 3

Correct Answer: (b) 1 and 2 only
Note:

Since x axis shows the distance and y axis shows the time, hence lower graph will show faster athlete and higher graph will show slower athlete. Height of A's graph is the lowest, hence, the race was won by A. Height of B's graph is lower than A's graph up to 25 km, hence B was running faster than A up to 25 km. The height of C's graph is the lowest from the beginning, hence he run very fastly from the beginning, Hence statement 3 is not correct.

25. Consider the following information regarding the performance of a class of 1000 students in four different tests: [2012-1]

Tests	I	II	III	IV
Average marks	60	60	70	80
Range of marks	30 to 90	45 to 75	20 to 100	0 to 100

If a student scores 74 marks in each of the four tests, in which one of the following tests is her performance the best comparatively?

(a) Test I
(b) Test II
(c) Test III
(d) Test IV

Correct Answer: (b) Test II
Note:

Tests	I	II	III	IV
Average Marks	60	60	70	80
Range of Marks	30 to 90	45 to 45	20 to 100	0 to 100

90 - 30 = 75, 75 - 45 = 30, 100 - 20 = 80, 110 - 0 = 110

If a student scores 74 marks in each of the four tests, his performance would be the best comparatively in test II because there would be less numbers of the students in this range in test II only.

26. Consider the following diagrams: [2013-1]

x men, working at constant speed, do a certain job in y days. Which one of these diagrams shows the relation between x and y?

(a) Diagram I
(b) Diagram II
(c) Diagram III
(d) Diagram IV

Correct Answer: (d) Diagram IV
Note:

Time taken to finish a work is inversely proportional to the number of persons working at it.

More persons then less is the time taken to finish a job. Hence, diagram IV represents the relation between x and y.

27. How many Physics professors belong to the age group 35 - 44 ? [2013-1]

Study the two figures given below and answer the questions that follow:

Fig 1: Number of Professors in selected disciplines in a University by sex :

Fig 1: Age of Physics Professors

(a) 18
(b) 16
(c) 14
(d) 12

Correct Answer: (b) 16
Note:

Number of professors in physics = 40

Percentage of professors in age group 35 - 44 = 40%

Physics professors belong to age group

35 - 44 = 40% of 40 = 16

28. Which one of the following disciplines has the highest ratio of males to females? [2013-11]

Study the two figures given below and answer the questions that follow:

Fig 1: Number of Professors in selected disciplines in a University by sex :

Fig 1: Age of Physics Professors

(a) Physics
(b) Mathematics
(c) Chemistry
(d) Economics

Correct Answer: (a) Physics
Note:

By looking to graph I. We can deduce that physics discipline has the highest ratio of males to females.

29. What percentage of all Psychology professors are females? [2013-1]

Study the two figures given below and answer the questions that follow:

Fig 1: Number of Professors in selected disciplines in a University by sex :

Fig 1: Age of Physics Professors

(a) 40%
(b) 50%
(c) 60%
(d) 70%

Correct Answer: (c) 60%
Note:

No. of females psychology professor = 6

No. of males psychology professor = 4

Required percentage = No. of females/Males+Females × 100

= 6/10 * 100 = 60%

30. If the number of female Physics professors in the age group 25-34 equals 25% of all the Physics professors in that age group, then what is the number of male Physics professors in the age group 25-347 [2013-11]

Study the two figures given below and answer the questions that follow:

Fig 1: Number of Professors in selected disciplines in a University by sex :

Fig 1: Age of Physics Professors

(a) 9
(b) 6
(c) 3
(d) 2

Correct Answer: (a) 9
Note:

Number of all physics professors in age group

25 - 34 = 30% of 40 = 30/100 * 40 = 12

Number of female physics professors in the age group

25 - 34 = 25% of 12 = 25/100 * 12 = 3

Number of male physics professors in the age group

25 - 34 = 12 - 3 = 9
