I think it should be C.

stmnt1
25h>=150
h>=6
insuffic.

stmnt2
8p+25h<260
insuffic.

Let's combine.
Since 8p+25h < 260, then 260-150 = 110 is the maximum amount to have been spent on paperbooks. Therefore, p<14.
From here, we can plug in numbers to calculate p and h. Doing so, we can see that the only combination is when h=4 and p=20.
So, it should be C.

I wonder if there's a faster way to do this final step, when we combine?

P and H
8P > 80

Statement 1 - 25H >= 150, H >= 6 - not sufficient
Statement 2 - 8P + 25H < 260 - not sufficient

Combining the 2 statements, 8P < 110, if we take H to be 6. We know that it is more than 10 Paper backs, so it can be either 11, 12 or 13. If it is 11, we can have 6 H - if it is 12, we can still have 6 H - and if it is 13, then also we can have 6 H. So all 3 satisfies the equation. If it was 7, then we wouldn't satisfy the clause for greater than 10 P.

So the answer is C. What is the OA?
