Identify Target Numbers
List: 5479, 3126, 6785, 9254, 1630. Sorting: 9254 > 6785 > 5479 > 3126 > 1630. Greatest = 9254, Second-Greatest = 6785, Smallest = 1630.
Extract Specific Digits
Second-greatest number is 6785. The 4th digit (from left) is 5. The smallest number is 1630. The 3rd digit (from left) is 3.
Perform Addition
Adding the extracted digits: 5 + 3 = 8.
A: 12 is incorrect as the calculated sum is 8. B: 10 is incorrect as the sum is 8. D: 14 is incorrect as the sum is 8.
C is correct because the 4th digit of the second-greatest number (6785) is 5, and the 3rd digit of the smallest number (1630) is 3, which sums to 8.
In competitive exams, always re-verify your sorting order (Greatest/Second-Greatest) before indexing, as a single digit error propagates through the entire calculation.
