Data Interpretation and Logical Reasoning flashcards for IIFT Entrance Exam

25 of 50 cards from the Data Interpretation and Logical Reasoning deck — real questions with worked answers.

1. In a data table, how do you calculate the percentage contribution of one row's value to a column total?

   Percentage contribution = (Cell value / Column total) x 100. It expresses what share that cell represents of the whole column.

2. When reading a table with year-on-year data, how is the growth rate from one year to the next computed?

   Growth rate = ((Current year value - Previous year value) / Previous year value) x 100.

3. What is the key advantage of a bar graph over a table for DI questions?

   A bar graph allows quick visual comparison of magnitudes across categories; the longer/taller the bar, the larger the value. It speeds up relative comparisons but loses exact precision.

4. On a line chart, what does the slope of a line segment between two points represent?

   The slope represents the rate of change (increase or decrease) between the two time periods; a steeper slope means a faster change, and a downward slope means a decline.

5. In a pie chart, how do you convert a sector's central angle into a percentage and a value?

   Percentage = (Angle / 360) x 100. Value = (Angle / 360) x Total. Conversely, Angle = (Value / Total) x 360 degrees.

6. In a pie chart, what central angle corresponds to 1% of the total?

   3.6 degrees, since 360 degrees / 100 = 3.6 degrees per percent.

7. What is a caselet in Data Interpretation?

   A caselet is a DI set where data is presented as a paragraph of text (no chart or table). The solver must extract and organize the figures, often into a table, before answering.

8. What is the recommended first step when solving a caselet (paragraph-based DI) problem?

   Read carefully and convert the textual data into a structured table or diagram, then identify relationships and solve. Organizing the data is essential before computation.

9. What is a mixed or combination chart in DI?

   A combination chart displays two or more chart types together (e.g., bars with a superimposed line), often using two y-axes, to show different but related data sets simultaneously.

10. In a combination chart with bars and a line, why is a secondary (right-hand) axis often used?

    The secondary axis is used when the two data series have very different scales or units (e.g., revenue in crores on bars and growth percentage on the line), so each can be read accurately.

11. What does a Data Sufficiency question ask you to determine?

    It asks whether the given statements provide enough information to answer the question, NOT to actually compute the final answer. You judge sufficiency, not the value.

12. State the five standard answer options used in Data Sufficiency questions.

    (A) Statement 1 alone is sufficient, 2 is not; (B) Statement 2 alone is sufficient, 1 is not; (C) Both together are sufficient, neither alone; (D) Each alone is sufficient; (E) Both together are still not sufficient.

13. In Data Sufficiency, what is a common trap regarding the two statements?

    Evaluating each statement independently before combining; people wrongly assume both are needed or carry information from one into the other. Each must first be judged alone, then together.

14. In Arrangement (linear) puzzles, what defines a linear arrangement and how are 'left' and 'right' interpreted?

    A linear arrangement places people/objects in a single row. Unless stated otherwise, directions are from the reader's perspective; if all face the solver, their left/right are reversed relative to the solver.

15. In a circular arrangement, how does the facing direction affect neighbor positions?

    If all face the centre, a person's left is the next anticlockwise and right is clockwise. If all face outward, this reverses. Mixed-facing requires tracking each person's orientation.

16. In Distribution and Grouping puzzles, what type of information must be tracked simultaneously?

    Multiple parameters per entity (e.g., person, plus attributes like city, colour, profession). A grid/matrix is used to map each entity to its attributes from the clues.

17. What technique is best for solving Distribution/matching puzzles with several categories?

    A matrix (grid) where rows are entities and columns are attributes; mark definite Yes (tick) and No (cross) cells, eliminating possibilities until each entity has a unique match.

18. In Scheduling and Ordering puzzles (e.g., days/months), what should you do with 'before/after' and 'between' clues?

    Translate them into relative positions on a sequence/timeline, fixing order constraints. 'Between' clues fix gaps; combine fixed anchors with relative ones to build the full order.

19. What is the difference between a 'ranking' and an 'ordering' puzzle?

    Ranking compares entities on a single measurable attribute (tallest, oldest, etc.) producing a top-to-bottom order; ordering arranges items by position/sequence such as days, floors, or queue places.

20. In Blood Relations, what relation is 'my father's only son'?

    It refers to the speaker himself (the male speaker). So 'father's only son' = me.

21. In Blood Relations, who is 'the daughter of my grandfather's only son' (assuming your father is that only son)?

    She is your sister (or yourself if you are female), since grandfather's only son is your father, and his daughter is your sister.

22. What is the standard convention for representing gender and generations in a blood-relation diagram?

    Use symbols: '+' or square for male, '-' or circle for female; horizontal lines (=) for married couples and siblings, vertical/sloped lines for parent-child links across generations.

23. In Directions and Distances, what are the four cardinal and four ordinal directions and their angular gaps?

    Cardinals: North, East, South, West (90 degrees apart). Ordinals: NE, SE, SW, NW, each 45 degrees between two cardinals.

24. In a Directions problem, how do you find the shortest (straight-line) distance after movements forming a right angle?

    Use the Pythagoras theorem: shortest distance = square root of (horizontal displacement squared + vertical displacement squared).

25. In Directions problems, if you face North and turn right, which direction do you face? And after a further right turn?

    Facing North, a right turn faces you East; a further right turn faces you South. Each right (clockwise) turn rotates you 90 degrees: N to E to S to W.
