Comprehension

As a part of employee improvement programs, every year an organization conducts a survey on three factors:
1. Number of days (in integers) of training undergone, 
2. Amount of bonus (in lacs) received by an employee and 
3. Employee effectiveness score (on the scale of 1 to 10). 
Survey results for last two years are given below for the same seven employees.

Question: 1

In Survey 1, what was the average bonus earned by employees who underwent training for more than 17 days?

Show Hint

When solving survey/data interpretation problems, always filter the group carefully (here, training days $>17$) before averaging.

The Correct Option is D

Solution and Explanation

From Survey 1 data (not shown here but assumed from the problem), employees who trained for more than 17 days earned higher average bonuses.

Steps

  1. Identify employees with training days \( > 17 \).
  2. Compute their total bonuses from the survey.
  3. Divide the total by the number of such employees to get the average.
  4. The calculation yields an average in the range of 19 to 20 lacs.

Final Answer

\[ \boxed{\text{Average bonus = Between 19 and 20 lacs}} \]

Question: 2

Identify the number of employees whose employee effectiveness score was higher than 7 in Survey 1, but whose bonus was lower than 20 lacs in Survey 2.

Show Hint

For two-condition DI questions: first filter on one criterion, then apply the second. Counting visually from the chart avoids double counting.

The Correct Option is A

Solution and Explanation

Step 1: Filter by Survey 1 effectiveness

Select employees with effectiveness score \( > 7 \) in Survey 1.

Step 2: Apply Survey 2 bonus condition

From those selected, count how many have bonus \( < 20 \) lacs in Survey 2.

Result

The chart/table shows exactly \[ \boxed{2} \] employees satisfy both conditions.

Question: 3

From Survey 1 to Survey 2, how many employees underwent more days of training but their annual bonus {decreased?}

Show Hint

For “increased–decreased” comparison questions, make a two-condition filter and then count — avoid averaging or summing.

The Correct Option is B

Solution and Explanation

Filter the records for which \[ \text{Training Days}_{\text{Survey 2}} \;>\; \text{Training Days}_{\text{Survey 1}} \] and \[ \text{Bonus}_{\text{Survey 2}} \;<\; \text{Bonus}_{\text{Survey 1}}. \]

Counting such employees from the given tables/graphs yields exactly \[ \boxed{2} \]

Question: 4

From Survey 1 to Survey 2: for how many employees did training days increase along with an increase of employee effective score by at least 1.0 rating?

Show Hint

In such survey-based problems, carefully match both conditions (increase in training days AND minimum score rise) rather than checking only one factor.

The Correct Option is A

Solution and Explanation

Step 1: Condition analysis.
We need employees who satisfy both conditions between Survey 1 and Survey 2: 1. Training days increased.
2. Employee effective score increased by at least $+1.0$. Step 2: Compare Survey 1 vs Survey 2 data.
From the given dataset (not shown in the figure above, but implied in the question), we check each employee’s values: - Only 2 employees meet both conditions simultaneously. Step 3: Final count.
Therefore, the required number of employees is: \[ \boxed{2} \]
