A
21six, 22three, 34five,
B
21six, 34five, 22three
C
22three, 34five, 21six
D
34five, 21six, 22three
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
22three, 34five, 21six = (2 x 3)(2 x 3o), (3 x 51) = (4 x 50), (2 x 61) + (1 x 60)
= (6 + 2), (15 + 4), (12 + 1) = 8ten, 29ten, 13ten in descending order
29ten, 13ten, 8ten = 34five, 21six, 22three
