(1/10)^n < 0.01 ?

Lets simplify this equation.

(1/10)^n < (1/10)^2

n<2?

(1) n>2 ======> Sufficient

(2) 1/10(n-1) < 0.1

n - 1 < 1

n < 2 ======> Suffiient

As both statements are sufficient answer is D

this is an old question...not sure if this has been mentioned here before but request someone to make a small addition in the question

I thought only 1 is raised to n and not the entire fraction 1/10...kindly add a bracket (1/10)^n to avoid any confusion
