2 .5
3 .333
4 .25

both n=3 and 6 satisfies both conditions hence E

(1) n is the tenth digit in the decimal representation of 1/n.
(2) n is the hundredth digit in the decimal representation of 1/n.
One decimal place to the right of the decimal point is the "tenths" place

As per liferocks' table
n 1/n
1 1
2 .5
3 .333
4 .25
5 .20
6 .166
7 .1428
8 .125
9 .111

(1) Possible only if n = 3
(2) Possible if n = 3 or 6

IMO A
