(1) says

10 + (n-1) > 30

=> n > 21

(1) is not sufficient as n could be 22 or 25

(2)

{10 + (n-1)}/n > 1.36

=> 9 + n > 1.36n

=> 0.36n < 9

=> 0.04n < 1

=> n < 25

Sufficient as n is an integer, so n !> 24

Sorry, I was doing another thing also on my system while posting this. Even then too, the answer is B, as you get the answer, n = 25, which is > 24. So we have a definite "Yes" as answer from (2).
