Analyzing Bank Vacant Posts and Cadre Breakup

The question asks us to compare the number of Law Officers (LOs) recruited in a specific group of banks (C, E, and F) with another group (A, B, and D) based on the provided data tables.

We are given two tables:

We are told that the cadre percentage breakup is the same for all six banks. We need to focus on the Law Officers (LO) cadre.

Calculating Law Officer (LO) Posts

From Table 2, the percentage of vacant posts for Law Officers (LO) is 10%.

We can calculate the number of LO posts in each bank by taking 10% of the total vacant posts for that bank from Table 1.

• LOs in Bank A = 10% of 800 = $\frac{10}{100} \times 800 = 80$
• LOs in Bank B = 10% of 940 = $\frac{10}{100} \times 940 = 94$
• LOs in Bank C = 10% of 600 = $\frac{10}{100} \times 600 = 60$
• LOs in Bank D = 10% of 820 = $\frac{10}{100} \times 820 = 82$
• LOs in Bank E = 10% of 450 = $\frac{10}{100} \times 450 = 45$
• LOs in Bank F = 10% of 560 = $\frac{10}{100} \times 560 = 56$

Comparing LO Recruitments by Bank Groups

Now we need to find the total number of LO recruitments for the two specified groups of banks.

Group 1: Banks C, E, and F taken together

Total LOs in C, E, and F = LOs in C + LOs in E + LOs in F

Total LOs (C, E, F) = $60 + 45 + 56 = 161$

Group 2: Banks A, B, and D taken together

Total LOs in A, B, and D = LOs in A + LOs in B + LOs in D

Total LOs (A, B, D) = $80 + 94 + 82 = 256$

Calculating the Percentage Difference

We need to find by what percent the number of recruitments of LOs in C, E, and F (Group 1) is more/less than in A, B, and D (Group 2).

Comparing the totals:

• Total LOs (C, E, F) = 161
• Total LOs (A, B, D) = 256

Since 161 is less than 256, the number of LO recruitments in C, E, and F is less than in A, B, and D.

The difference in the number of LOs is: $256 - 161 = 95$

To find the percentage difference "than in A, B and D taken together", we use the total for A, B, and D (256) as the base for the percentage calculation.

Percentage Difference = $\frac{\text{Difference}}{\text{Total LOs (A, B, D)}} \times 100$

Percentage Difference = $\frac{95}{256} \times 100$

Percentage Difference $\approx 0.37109375 \times 100 \approx 37.11\%$

Since the number of LOs in C, E, and F is less than in A, B, and D, the number of recruitments is less by approximately 37.11%.

Conclusion

The number of recruitments of LOs in C, E, and F taken together is less than in A, B, and D taken together by approximately 37.11%.

Revision Table: Key Calculations

Additional Information on Data Interpretation

Data interpretation questions often involve analyzing data presented in tables, charts, or graphs to answer specific questions. Key skills required include:

• Understanding the Data: Carefully read the titles, labels, and notes for all tables or figures provided. Understand what each number or category represents.
• Identifying Relevant Information: Not all data provided may be needed for every question. Focus only on the data points required to solve the problem. In this question, we focused on the total vacant posts per bank and the percentage for the Law Officer cadre.
• Performing Calculations: Based on the question, perform necessary calculations such as percentages, averages, ratios, sums, or differences. Ensure calculations are accurate.
• Comparing Values: Many questions require comparing values or groups of values to find differences, percentages more/less, ratios, etc.
• Careful Reading of the Question: Pay close attention to what is being asked. For percentage differences, note which value is the base for the calculation (e.g., "% more/less than X" means X is the base).

Practicing with different types of data representation (tables, bar graphs, pie charts, line graphs) and different types of questions (percentage change, ratio, average, specific value calculation) helps build proficiency in data interpretation for exams.
