Arrange the following numbers in descending orders of magnitude: 22three, 34five, 21six

A.

21six, 22three, 34five,

B.

21six, 34five, 22three

C.

22three, 34five, 21six

D.

34five, 21six, 22three

Correct answer is D

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
