I say answer is B.

1/33 = 0.030303
1/32 ~ 0.03... <-- The digits after hundredths place are going to increase in value as denominator decreases from 33 to 31
1/31 ~ 0.03...

So, the middle part of the expression will be 0.09 and some extra bits

From answer choices, we want an "n" value that will have a reciprocal greater than 0.09.. Since 0.09 < 1/n

Both A and B satisfy this.

However, we must discount A because the left side of expression, that is, 1/(n+1) will result in 1/(1+9) = 0.10. This will not satisfy the condition.

Now we are left with B as answer choice. I hope it is the correct one... Can you confirm anjali?
