How do you solve this one?

(1) The hundreds digit of 10n is 6 SUFFICIENT: If Hundred's place of 10n = 6 then Ten's place of n must be 6 e.g. n=68 tens place 6, 10n=680, hundreds place is 6

(2) The tens digit of n+1 is 7 INSUFFICIENT: If n=69; n+1=70 OR If n=77; n+1=77; i.e. n can have both 6 or 7 as tens place.
