Test: Data Interpretation - 2 (2014-2011) - Question 8

Consider the following diagrams:
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?
 

[2013]

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.

Test: Data Interpretation - 2 (2014-2011) - Question 9

Consider the following information regarding the performance of a class of 1000 students in four different tests:

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?

[2012]

Detailed Solution for Test: Data Interpretation - 2 (2014-2011) - Question 9


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.

Test: Data Interpretation - 2 (2014-2011) - Question 10

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

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?

[2011]

Detailed Solution for Test: Data Interpretation - 2 (2014-2011) - Question 10

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.

Test: Data Interpretation - 2 (2014-2011) - Question 14

Consider the following Velocity – Time graph. It shows two trains starting simultaneously on parallel tracks.

With reference to the above graph, which one of the following statements is not correct?

[2011]

Detailed Solution for Test: Data Interpretation - 2 (2014-2011) - Question 14

Distance = time x speed, here train B is faster than train A, hence Train B will cover more distance than train A.

Test: Data Interpretation - 2 (2014-2011) - Question 15

The following pie charts show the break up of disease categories recorded in the patients from two towns, Town A and Town B. Pie charts plot the disease categories as percentage of the total number of patients. Based on these answer the two items that follow the charts.
