Passage
The Sustainability Index (SI) of a country at a point in time is an integer between 1 and 100. This question is related to SI of six countries - A, B, C, D, E, and F - at three different points in time - 2016, 2020, and 2024. The plot represents the exact changes in their SI, with X-coordinate representing % increase in 2020 from 2016, i.e., (SI in 2020 minus SI in 2016) / (SI in 2016), and Y-coordinate representing % increase in 2024 from 2020. At any point in time, the country with highest SI is ranked 1, while the country with the lowest SI is ranked 6. The following additional facts are known.
- In 2016, B, C, E, and A had ranks 1, 2, 3, and 4 respectively.
- F had lower SI than any other country in 2016, 2020, and 2024.
- In 2024, E was the only country with SI of 90.
- The range of SI of the six countries was 60 in 2016 as well as in 2024.

Passage
The different bars in the diagram above provide information about different orders in various categories (Art, Binders, ….) that were booked in the first two weeks of September of a store for one client. The colour and pattern of a bar denotes the ship mode (First Class / Second Class / Standard Class). The left end point of a bar indicates the booking day of the order, while the right end point indicates the dispatch day of the order. The difference between the dispatch day and the booking day (measured in terms of the number of days) is called the processing time of the order. For the same category, an order is considered for booking only after the previous order of the same category is dispatched. No two consecutive orders of the same category had identical ship mode during this period.
For example, there were only two orders in the furnishing category during this period. The first one was shipped in the Second Class. It was booked on Sep 1 and dispatched on Sep 5. The second order was shipped in the Standard class. It was booked on Sep 5 (although the order might have been placed before that) and dispatched on Sep 12. So the processing times were 4 and 7 days respectively for these orders.
Q5.CAT 2021How many days between Sep 1 and Sep 14 (both inclusive) had no booking from this client considering all the above categories?
Answer: 6
- Q6.CAT 2021
What was the average processing time of all orders in the categories which had only one type of ship mode?
Answer: 11
- Q7.CAT 2021
The sequence of categories -- Art, Binders, Paper and Phones -- in decreasing order of average processing time of their orders in this period is:
Art, Binders, Paper, Phones
Phones, Art, Binders, Paper
Phones, Binders, Art, Paper
Paper, Binders, Art, Phones
- Q8.CAT 2021
Approximately what percentage of orders had a processing time of one day during the period Sep 1 to Sep 22 (both dates inclusive)?
22%
16%
20%
25%
Passage
Schedule of the four employees across the five projects — each bar runs from the start to the end month of that employee’s work; the number on it is the percentage of assigned work completed.
The figure above shows the schedule of four employees - Abani, Bahni, Danni, and Tinni - whom Dhoni supervised in 2020. Altogether there were five projects which started and concluded in 2020 in which they were involved. For each of these projects and for each employee, the starting day was at the beginning of a month and the concluding day was the end of a month, and these are indicated by the left and right end points of the corresponding horizontal bars. The number within each bar indicates the percentage of assigned work completed by the employee for that project, as assessed by Dhoni.
For each employee, his/her total project-month (in 2020) is the sum of the number of months (s)he worked across the five projects, while his/her annual completion index is the weightage average of the completion percentage assigned from the different projects, with the weights being the corresponding number of months (s)he worked in these projects. For each project, the total employee-month is the sum of the number of months four employees worked in this project, while its completion index is the weightage average of the completion percentage assigned for the employees who worked in this project, with the weights being the corresponding number of months they worked in this project.
Q9.CAT 2021Which of the following statements is/are true?
I: The total project-month was the same for the four employees.
II: The total employee-month was the same for the five projects.Only II
Both I and II
Neither I nor II
Only I
- Q10.CAT 2021
Which employees did not work in multiple projects for any of the months in 2020?
Only Abani, Bahni and Danni
Only Abani and Bahni
All four of them
Only Tinni
- Q11.CAT 2021
The project duration, measured in terms of the number of months, is the time during which at least one employee worked in the project. Which of the following pairs of the projects had the same duration?
Project 1, Project 5
Project 4, Project 5
Project 3, Project 5
Project 3, Project 4
- Q12.CAT 2021
The list of employees in decreasing order of annual completion index is:
Danni, Tinni, Bahni, Abani
Bahni, Abani, Tinni, Danni
Danni, Tinni, Abani, Bahni
Tinni, Danni, Abani, Bahni
