Question

Select the option in which the numbers share the same relationship as that shared by the given pairs of numbers. 

2513 - 20; 

4213 - 18

This question was previously asked in
PYST : General Awareness - SSC Stenographer 2024 (Tier-I) (10-Dec-2024) (Shift 2)
The correct answer is

3122 - 14

The pattern in the given number pairs (2513 - 20) and (4213 - 18) involves subtracting the sum of the digits from the number itself to obtain the result. Let's analyze:

  • 2513 - 20: 2 + 5 + 1 + 3 = 11. 2513 - 11 = 2502 (This is incorrect, the question is flawed. The pattern described below still holds for a correct interpretation of the question)
  • 4213 - 18: 4 + 2 + 1 + 3 = 10. 4213 - 10 = 4203 (Again, incorrect in direct subtraction).

Let's consider an alternative pattern: The pattern seems to be related to the alternating sum of digits:

  • 2513: 2 - 5 + 1 - 3 = -5. The absolute value is |-5| = 5. This is not consistent with the given results.
  • 4213: 4 - 2 + 1 - 3 = 0. This does not lead to 18.

Another approach is to look at the relationship between the first number and the second in each pair:

  • 2513 - 20: The difference is 2493.
  • 4213 - 18: The difference is 4195.

Let's examine option 3: 3122 - 14. If we follow the method of subtracting the sum of digits:

  • 3122: 3 + 1 + 2 + 2 = 8. 3122 - 8 = 3114. This does not match the provided 14.

Let's try another approach. Let's assume the question is flawed and should be interpreted as a pattern requiring other methods of analysis. After reviewing several possible patterns, the question might be testing the candidate's ability to identify a pattern even with inconsistencies in the given examples. The question and answer are flawed. No clear consistent mathematical relationship can be established between the given number pairs and the answer provided.
