This is really a tough one. Whenever you see such question there is always a pattern underlined it.

now we do know that x -1 and x are consecutive positive integers.

if you pick a number you will see the pattern

1 and 2. follow that for x/4 x = 2 which means 2/4 = 1/2 = 0.50 and the tenth digit is 5 is always greater than the zero. 5 > 0 (zero is the hundredths digit)

2 and 3. follow that for x/4 you do have 3/4 = 0.75 and 7 > 5

5 and 6. follow that for x/4 you do have 6/4 = 3/2 = 1.50 and 5 > 0

and so on and so forth this pattern.

Therefore, the tenth digit is always greater than the hundredth digit

A is the answer
