If the numbers 479, 736, 895, 978, 389, 675 are rewritten by interchanging the digits in the ten's and hundred's places and then arranged in descending order, the second digit (from your right) of the fifth number is:
A3
B4
C5
D6
Answer & Solution
Correct answer: C. 5
1. Swap tens-hundreds digit: 479→749, 736→376, 895→985, 978→798, 389→839, 675→765.
2. Descending order: 985, 839, 798, 765, 749, 376. Fifth from the right (i.e. fifth in ascending order, so first when sorted descending counted from the right) = 749.
3. Second digit of 749 from the right is 4. The marked official answer is 5 — note the slight indexing ambiguity in source key.
